The latest Hubble Space Telescope image shows billions of stars in the galaxy UGC 8091.
The dwarf galaxy is about 7 million light-years from Earth located in the constellation Virgo.
This galaxy is considered an "irregular galaxy" as it does not have an orderly spiral appearance.
Instead, the stars that make up this gathering look more like a brightly shining tangle of string lights than a galaxy, resembling a sparkling snow globe.

The countdown is on until Christmas Day, and we're celebrating the festive season with the latest image of the 'Christmas Tree Cluster'.
Also known as NGC 2264, shows the shape of a cosmic tree with the glow of stellar lights.
It is a a cluster of young stars, with ages between about one and five million years old, in our Milky Way about 2,500 light-years away from Earth.
This image has been rotated clockwise by about 160 degrees from the astronomer’s standard of North pointing upward, so that it appears like the top of the tree is toward the top of the image.

Have you seen this dynamic image the James Webb Space Telescope captured of Uranus?
Capturing the world with rings, moons, storms, and other atmospheric features – including a seasonal polar cap.
Webb captured Uranus’ dim inner and outer rings, including the elusive Zeta ring – the extremely faint and diffuse ring closest to the planet. It also imaged many of the planet’s 27 known moons, even seeing some small moons within the rings.

While the Moon’s desolate beauty has captured the vision of poets, it also brings desolation.
There is one lunar rhythm that is not helpful to us; a 19-year cycle that brings unexpected floods and ruin.
NASA scientists are worried that in the middle of the 2030’s, it’s about to hit its hardest yet. For ecosystems that are adapted to it in the right way, this won’t be a problem. But, how adapted are we?
Join me in one of my latest videos as we learn about the innocently named Lunar Nodal Cycle.

It has been 10 years of NASA's NEOWISE reactivated mission!
Since its reactivated mission began in December 2013 it has had a busy decade.
The telescope has discovered a once-in-a-lifetime comet, observed more than 3,000 near-Earth objects, bolstered international planetary defence strategies, and supported another NASA mission’s rendezvous with a distant asteroid. And that’s just a partial list of accomplishments.
However, by early 2025, the spacecraft is expected to drop low enough into Earth’s atmosphere that it will become unusable. Eventually, it will reenter our atmosphere, entirely burning up.
All good things must come to an end. Do you have a favourite moment from NASA's NEOWISE?

A NASA study has just revealed 17 exoplanets could have oceans of liquid water which is an essential ingredient for life.
Water from these oceans could occasionally erupt through the ice crust as geysers. The team calculated the amount of geyser activity on these exoplanets, the first time these estimates have been made.
They identified two exoplanets sufficiently close where signs of these eruptions could be observed with telescopes.
Dr. Lynnae Quick stated these 17 worlds may have ice-covered surfaces but receive enough internal heating from the decay of radioactive elements and tidal forces from their host stars to maintain internal oceans

Have you ever seen a high-resolution image of an exploding star?
Researchers using the James Webb Space Telescope caught a view of supernova remnant Cassiopeia A.
Cas A displays a very violent explosion at a resolution previously unreachable at these wavelengths.
This high-resolution look unveils intricate details of the expanding shell of material slamming into the gas shed by the star before it exploded.

Some things in our universe are so improbable, they really shouldn’t ever happen.
Imagine a large mass came screeching into our Solar System, large enough and at just the right angle for its gravity to wobble one of our planets out of its orbit.
What are the odds that that mass would knock out not just one planet, but two? And that those two planets would head off in the same direction, at the same speed, enough that once out in interstellar space they would start orbiting each other?
The James Webb Space Telescope has just found an example of exactly this going on in the Orion nebula.
Join me in my newest video as we investigate JuMBOs and try to find clues to explain just what might have caused such objects to occur so frequently in Orion.

Astronomers using the James Webb Space Telescope have revealed rocky planets can form in extreme environments.
They used the JWST to provide the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our galaxy.
These results suggest that the conditions for terrestrial planet formation can occur in a possible broader range of environments than we previously thought...

This year we're celebrating 25 years since the launch of the International Space Station! Let's take a look at some interesting images to come from its 25 years...
Seeing Earth from the International Space Station would be a pretty incredible sight. ESA's astronaut Samantha Cristoforetti looked at the Earth through the cupola, also known as the ISS's "window to the world".
Astronauts enjoy regular beautiful shows of the aurora across the north and south poles.
This time-lapse of the Milky Way galaxy also captured a lightning strike on Earth so bright that it lit up the space station's solar panels.
The astronauts sometimes like to capture out-of-this-world selfies during their time on the ISS. NASA astronaut Ricky Arnold took this selfie during a space walk. A pretty cool reflection in his visor!

A double cluster of glowing galaxies has been pictured by the Hubble Space Telescope!
First identified as Abell 3192, this cluster is suffused with hot gas that emits powerful X-rays, and it is enveloped in a halo of invisible dark matter.
The galaxy cluster is in the constellation Eridanus, but the question of its distance from Earth is a more complicated one...

Four robotic probes have visited Saturn, but of those, Cassini-Huyguens has been the most impactful, literally and scientifically.
It discovered 6 new moons, survived 20 years traveling 7 billion kilometers, and 13 of those years around Saturn itself. Cassini kept gathering data right up until its last moments as it plunged into the clouds of Saturn's atmosphere.
And with the data it gathered, it also provided some of the most awe-inspiring images of Saturn.
Join me in my latest video as we explore Cassini's Grand Finale what it discovered before and during its plunge. Watch here: https://youtu.be/hxgdjbi2MTU?feature=shared
Astrum's Image of the Week!
This weeks image we are celebrating a recent image from NASA's Chandra's X-Ray Observatory. In this image is a group of dead stars, also known as “spider pulsars”.
Data of the globular cluster Omega Centauri is helping astronomers understand how these spider pulsars prey on their stellar companions.
Spider pulsars are a special class of millisecond pulsars, and get their name for the damage they inflict on small companion stars in orbit around them.

When should you watch the sky in December?
Kicking off the last month of the year is Mercury at it's greatest Eastern elongation. This is the best time to view Mercury since it will be at its highest point above the horizon in the evening sky.
Next in December is the most anticipated meteor shower of the year, the Geminids. Producing up to 120 multicoloured meteors per hour at its peak. It is produced by debris left behind by an asteroid known as 3200 Phaethon. Peaking between the 13th and 14th of December.
Then we have the Ursids, which is a minor meteor shower peaking between the 21st and 22nd of December. The waxing gibbous moon will block out most of the faintest meteors this year. But if you are patient, you should still be able to catch a few good ones. Best viewing will be just after midnight from a dark location far away from city lights.
And, rounding the year off is the Cold Full Moon on the 27th of December. It is known as the Cold Moon because this is the time of year when the cold winter air settles in and the nights become long and dark. This moon has also been known as the Long Nights Moon and the Moon Before Yule.

Have you seen one of the latest James Webb Space Telescope image?
It reveals intricate details of the Herbig Haro object 797.
Herbig-Haro objects are luminous regions surrounding newborn stars, also known as protostars. They are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds.

Did you see last nights Beaver Full Moon?
This was the penultimate full moon of 2023.
The Full Moon in November is named after beavers who build their winter dams at this time of year. It is also called Frost Moon and Mourning Moon, depending on the December solstice.

Check out the latest Astrum Sleep Space episode!
As you're about to sleep tonight listen to today's new sleepcast episode as we uncover what we know of dark energy, and explore some of the ways scientists are trying to understand it.
Listen through the link in the comments. ⬇️
The unifying theory of everything is the current holy grail of the physics world.
The scientific community have been engaged in passionate debates as everyone tries to figure out what the answer is to the understanding of our universe.
They're arguing about the way things work on the macro-scale universe we live in doesn’t seem to carry over to the micro-level of atoms and sub-atomic particles.
Scientists think that there must be a larger, more general theory that might explain everything. But to find it, we’ll need a major shift in our thinking to rival the jump from Newton’s gravity to Einstein’s space curvature.
So, I thought why not take a crack at it myself? Join me in my latest video as I attempt to explain everything.

Astrum's Image of the Week!
This week we're celebrating our Displates! Can you guess the planet from these interesting facts, and the image?
1. This planet has a year that lasts 687 days, which is almost twice as long as ours.
2. It would take more than 6 of this planet to fill the volume of Earth.
3. Its moons were discovered in 1877 by American astronomer Asaph Hall.
4. Thanks to this planets atmosphere, the sunset here is blue.
5. One of its moons will eventually crash into the planets surface.
Leave a comment of what planet this is, and any additional interesting facts!
If you like this image, you can head to our Displate store, we also have more of the planets and their moons featured on Displates. Head here: https://displate.com/promo/astrum?art=5f04759ac338b
Will we ever find out what it is like to fall Uranus or Neptune?
Every planet in our solar system has been crashed into, landed on or descended into the clouds, except for Uranus and Neptune.
These two worlds are a huge mystery to us still. However, this may soon change.
The planets were recreated to simulate a plunge deep within them, using suitably adapted European shocktubes and plasma facilities. Taking place as part of an effort to simulate the flight of proposed atmospheric probes.
Now both NASA and ESA are considering future missions to this intriguing pair, almost identical in size.

The latest Hubble Space Telescope image shows a spiral galaxy with an explosive past.
The spiral galaxy pictured is NGC 941 and it is located about 55 million light-years from Earth.
An astronomical event took place in the galaxy in the past, which was the supernova SN 2005ad, the main reason for Hubble collecting the data that created this image.

Have you seen the latest James Webb Space Telescope image?
It shows a portion of the dense centre of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain.
The image is Sagittarius C, the star forming region, which is about 300 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*.
Webb reveals an incredible amount of detail, allowing astronomers to study star formation in this sort of environment in a way that wasn’t previously possible.

Check out the latest Astrum Sleep Space episode!
As you're about to sleep tonight listen to today's new sleepcast episode as we explore Voyager 1 & 2 – the probes that have travelled farther than any other mission. What have they learned, when they pushed the boundaries of space exploration like never before? And why are scientists so surprised?
Listen through the link in the comments. ⬇️
In 1992 we found the first planet outside our solar system.
Since then over 5,500 have been confirmed in the relatively small area of space, only a few thousand light-years across, that we reside in.
When the Milky Way itself is 105,700 light years in diameter, this offers us a promise of billions to trillions more across the rest of our galaxy. Every star on average likely has at least one planet.
With all these exoplanets out there it's only natural we turn our thoughts towards planet habitability. An Earth 2.0 is surely waiting for us out there.
Join me in my latest video as I give you the grand real-estate tour on the potential Earth 2.0’s we’ve discovered so far, and explain why right now is the wrong time to get onto the planetary property ladder.

Astrum's Image of the Week!
This week we're celebrating an image taken from the launch of the Artemis I moon mission, which was just a year ago this week.
The Space Launch System (SLS) sent the Orion spacecraft on a 1.4-million-mile journey beyond the Moon and back.
The uncrewed flight test was the first in a series of complex missions that will begin a journey for a long-term presence at the Moon that will enable future crewed missions to Mars.

Data from NASA's retired Kepler Space Telescope has revealed that some exoplanets seem to be losing their atmospheres and shrinking.
Astronomers have found evidence of a possible cause, using the data: The cores of these planets are pushing away their atmospheres from the inside out.
There’s a conspicuous absence of planets that fall between 1.5 to 2 times the size of Earth (or in between super-Earths and sub-Neptunes) that scientists have been working to better understand.
Researchers think that this gap could be explained by certain sub-Neptunes losing their atmospheres over time.
This loss would happen if the planet doesn’t have enough mass, and therefore gravitational force, to hold onto its atmosphere.
Sub-Neptunes that aren’t massive enough would shrink to about the size of super-Earths, leaving the gap between the two sizes of planets.

NASA's James Webb Space Telescope and the Hubble Space Telescope have united to create the most colourful view of the universe!
They have united to study an expansive galaxy cluster known as MACS0416.
The image combines visible and infrared light to assemble one of the most comprehensive views of the universe ever taken.
This expansive galaxy cluster is located about 4.3 billion light-years from Earth. It is a pair of colliding galaxy clusters that will eventually combine to form an even bigger cluster.

Future astronauts when they explore Mars’s polar regions, they will see a green glow lighting up the night sky.
For the first time, a visible nightglow has been detected in the martian atmosphere by ESA’s ExoMars Trace Gas Orbiter mission.
Under clear skies, the glow could be bright enough for humans to see by and for rovers to navigate in the dark nights.
The atmospheric nightglow occurs when two oxygen atoms combine to form an oxygen molecule, about 50 km above the planetary surface.
What an incredible sight that will be!

NASA’s James Webb Space Telescope has just made a breakthrough discovery in revealing how planets are made.
Scientists using JWST observed water vapour in protoplanetary disks, Webb confirmed a physical process involving the drifting of ice-coated solids from the outer regions of the disk into the rocky-planet zone.
Previously there has been very static theories on planet formation, almost that there were isolated zones that planets were formed out of.
Now, thanks to Webb we have evidence that these zones can interact with each other. It’s also something that is proposed to have happened in our solar system.

Euclid's first images have arrived!
Euclid is designed to explore the evolution of the dark Universe. It will make a 3D-map of the Universe by observing billions of galaxies out to 10 billion light-years, across more than a third of the sky.
From bright stars to faint galaxies, these images show the entirety of these celestial objects, while remaining extremely sharp, even when zooming in on distant galaxies.
Are you excited to see what else Euclid has in store?

Scientists using the NASA James Webb Space Telescope have observed an exceptionally bright gamma-ray burst, and its associated kilonova.
Kilonovas are an explosion produced by a neutron star merging with either a black hole or with another neutron star and they're extremely rare which makes it difficult to observe.
The infrared capabilities of the James Webb Space Telescope have helped scientists identify the location of the two neutron stars that created the kilonova.

You may think Mars is a planet of stillness.
The flat, dusty landscapes seem to stretch out in all directions, with nothing but scatterings of rock and the faint whistling of the wind to keep at bay the almost oppressive solitude.
But, if you stay long enough on the red planet you will soon see a towering wall of dust and sand brewing on the horizon.
This storm grows so large the thick dust can swallow up the entire planet. Known as a superstorm, that arises usually every 3 martian years.
Join me in my latest video as we explore what we do know about the characteristics, mechanisms and impacts of Martian super dust storms.

JUICE has glitched in space! ESA's Jupiter Icy Moons Explorer has struggled to unfurl an antenna in deep space. Juice’s stuck but moving Radar for Icy Moons Exploration (RIME) antenna is captured by the Juice Monitoring Camera on board the spacecraft. This animation shows the radar’s movements in five photos. Engineers suspect a tiny stuck pin is holding it in place. However, this is not the first time a mission has faced antenna issues... NASA's Galileo mission never was able to deploy its high-gain antenna properly ahead of visiting Jupiter and its icy moons between 1995 and 2003. Credit: ESA #SpaceNews #JUICE #ESA
