Why is there is a universe at all? The question is a challenging one because it seems perfectly possible that there might have been nothing whatsoever – no Earth, no stars, no galaxies, no universe.

Astronomers announced this month that a new deep-field survey called JADES will be carried out with the James Webb Space Telescope, Hubble's much-anticipated successor. The Webb is due to launch later this year.

Most of the planets in our solar system have some sort of atmosphere and many have dynamic weather systems. But only one moon in the solar system, Saturn's large moon Titan, can say the same.

On Monday, February 1, 2 NASA astronauts will perform the 2nd in a pair of International Space Station spacewalks to finish installing a European science platform and complete long-term battery upgrade work. How to watch live.

In November, a new mini-moon began orbiting Earth. NASA later confirmed it's a lost-and-found 60s-era rocket from the Surveyor 2 moon mission, launched more than 50 years ago. Now the object - SO 2020 - is coming close again for one last time. Here's how to see it!

Astronomers have discovered a possible newly-born planet forming within its own "whirlpool" of dust and pebbles, in orbit around a young star 330 light-years from Earth.

Earth has had at least 5 major ice ages. Now it appears Mars - the next planet outward from the sun - has undergone anywhere from half a dozen to 20 ice ages in the past several hundred million years.

This morning - Wednesday, January 27 - 2 NASA astronauts perform the first in a pair of International Space Station spacewalks, to finish installing a European science platform and complete long-term battery upgrade work.

In the animation in this post, the rhythmic movement of newly discovered planets around the star TOI-178 is represented through a musical harmony, created by attributing a note (in the pentatonic scale) to each of the planets. Hear the music of these planets.

A new study of the seven Earth-sized exoplanets around TRAPPIST-1 indicate that all 7 planets are extremely similar to each other in makeup, but potentially quite different from Earth.
