Via @galaxies What is going on in that solar system?🪐⚠️Explanation: The HR 8799 star system is home to four giant planets, each comparable in size to Jupiter, with orbital periods stretching from several decades to hundreds of years. Researchers are closely observing the system to determine its dynamic stability.
The video showcases a series of 10 images captured of HR 8799 using the Keck Telescope over a span of 12 years. It was created by Jason Wang, with data processing by William Thompson and Christian Marois, and observational coordination by Quinn Konopacky. Bruce Macintosh, Travis Barman, and Ben Zuckerman contributed to the observational efforts. (Credit to jasonwang.space).

By @statista On December 2, 2008, Google released the first version of the Chrome browser for Windows XP - four years later, it was already the most widely used web browser in the world. Today, with a market share of around 65.4 percent, Chrome is far ahead of all other browsers. Alongside the search engine and the YouTube video portal, Chrome is probably one of the US company's biggest success stories.
Previously, the majority of internet users surfed the web with Internet Explorer. But that was quite a while ago. According to StatCounter, the heyday of Internet Explorer was history with the rise of Chrome.
Germany was generally regarded as a Firefox stronghold. Accordingly, it took until the fall of 2017 for Chrome to overtake Firefox, the market leader at the time. Today, however, Chrome is clearly the most widely used browser in Germany too.

Via • @sciencealert Is it just us, or is this really satisfying to watch? 😌
The video was created thanks to the collective work of a large number of geological researchers around the world: more info about the researchers and the huge effort that went into this recreation via link in bio.

By • @thespace192 It is called Analemma!
An analemma is a curve or figure-eight shape that represents the position of the Sun in the sky over the course of a year. It's a graphical representation of the Sun's apparent motion due to the Earth's tilt and orbit around the Sun.
Here's how it works:👇
1. Imagine taking a photo of the Sun at the same time every day, from the same location, over the course of a year.
2. Plot the position of the Sun in each photo on a graph or map.
3. The resulting curve is an analemma, showing the Sun's apparent motion in the sky.
The analemma has several interesting features:👇
1. The curve resembles a figure-eight, with the top loop representing the summer months and the bottom loop representing the winter months.
2. The analemma intersects the celestial equator at the equinoxes and reaches its maximum distance from the equator at the solstices.
3. The analemma can be used to correct the equation of time, which is the difference between solar time and clock time.

By • @spacescience The illusion is called Fata Morgana and it's caused by warm air that is resting on patches of cold air in an atmospheric duct. This means that when you see something on the horizon, it can appear to be mirrored, floating or otherwise distorted due to this air acting like a refracting lens.

By • @galaxies This is because hurricanes rely on the Coriolis force to form and maintain their rotation. The Coriolis force is a result of the Earth’s rotation and causes objects in motion to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection is what helps hurricanes spin and develop their characteristic spiral shape. Since the Coriolis force is weaker near the equator, hurricanes are unable to form or maintain their structure if they were to cross the equator.
By • @mathsolverr Cartesian Coordinates
- Cartesian coordinates use two (or three for 3D) perpendicular axes: typically called the x-axis (horizontal) and the y-axis (vertical).
- Any point on a plane is defined by how far along it is on these two axes.
- You describe a point by giving its x (horizontal) and y (vertical) positions.
- For example, the point (3, 2) is 3 units to the right and 2 units up from the origin (0, 0), which is the point where the x-axis and y-axis intersect.
Polar Coordinates
- Polar coordinates describe a point based on its distance from a fixed central point (called the origin) and the angle from a reference direction (usually the positive x-axis).
- You describe a point by giving its distance from the origin (r) and the angle (θ) from the positive x-axis.
- For example, a point with coordinates (5, 45°) is 5 units away from the origin and at an angle of 45 degrees from the positive x-axis.
Cartesian Coordinates are great for:
- Problems involving straight-line movements.
- Easily adding or subtracting positions.
- Making rectangular or square grids.
Polar Coordinates are great for:
- Problems involving circular or rotational movements.
- Describing points in circular paths or angles.
- Working with trigonometry and waves.
In simple terms, Cartesian coordinates are like giving street directions using blocks (right/left, up/down), while polar coordinates are like giving directions using distance and angle (how far and which direction to go from a central point).
