Many planets in our solar system have an atmosphere. Earth has a lovely one filled with Nitrogen and Oxygen, while Mars and Venus have atmospheres primarily made of Carbon Dioxide. Even Pluto, which is only 1/6th the size of Earth, can hold onto a thin atmosphere at certain times of the year.But eventually we reach a point where an object is too small to have an atmosphere… Or so we thought!

It’s starting to feel like fall! The days are getting shorter, the nights are getting longer, and I started my day with a pumpkin spice latte. But when does Fall officially begin? If you’re using the astronomical definition, it happens on the Fall equinox, which is September 22nd this year.

We’ve known for nearly a century that there’s something strange hiding in our universe. Galaxies rotate too quickly. Galaxy clusters have too much gravity. And galaxy formation theories just don’t make sense without some invisible source of mass. We call this mysterious stuff dark matter. We know it must exist because we see its gravitational effects, but we’ve never actually detected a dark matter particle.Now, physicists may have finally caught one.

We’ve all looked up at the night sky in search of Orion, the mighty hunter. Three stars in a straight line signify Orion’s belt, with four additional stars making a big rectangle around it completing Orion’s body. The top left star of the rectangle is Betelgeuse, and it represents either the shoulder or armpit of the hunter...

NASA will soon be launching another amazing mission- the Nancy Grace Roman Space Telescope.

A few weeks ago, people in Europe, Iceland and Greenland got to see a total solar eclipse. But here in the United States, we only got to see a tiny bit of the sun covered by the moon. That’s ok though, because on Thursday, August 27th, everyone in North and South America will get to see a partial lunar eclipse!

Beta Pictoris is a pretty famous star amongst astronomers. It’s a young star visible in the southern hemisphere, and it’s surrounded by a disk of gas and dust that is actively forming planets. It was the first young star to ever have its debris disk photographed at visible wavelengths, way back in 1984.

The next total solar eclipse is this Wednesday, August 12, 2026!When the moon passes exactly between and the Sun and Earth, it casts a small shadow back down onto our planet. People standing under the direct shadow get to enjoy a total solar eclipse, while those under the extended shadow only get to see a partial solar eclipse.https://science.nasa.gov/eclipses/future-eclipses/

Our sun. It’s a small, middle aged star generating tons of energy. And right now it’s in a pretty perfect balance. Every day, the sun fuses hydrogen into helium in its core, and releases the same amount of energy at the surface.

Astronomers have discovered lots of planets that we call Hot Jupiters. These are gas giant planets outside the solar system that sit extremely close to their star, taking only a few days or weeks to orbit.Read more at- https://www.universetoday.com/articles/jwst-finds-methane-atmosphere-on-temperate-exoplanet
