Stars begin to expand when they run out of fuel and can become thousands of times larger, consuming any planets in the way. For the first time, astronomers have witnessed one such event.
Euclid is set to launch this year on a rocket built by SpaceX.

Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
All human development, from large cities to small towns, shines light into the night sky.
With the help of thousands of citizen scientists, a new study measured exactly how much brighter night skies are getting every year.
There are more than 100 missions to the Moon planned in the coming years, including the next Artemis missions.
With more than 100 lunar missions planned in coming years, space junk near the Moon could become an issue for humanity. No agency tracks lunar space junk, so two astronomers decided to do it themselves.
This cluster of galaxies, called Stephan’s Quintet, is a composite image produced from two cameras aboard the James Webb Space Telescope.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.
The mirror on the James Webb Space Telescope is fully aligned and producing incredibly sharp images, like this test image of a star.

It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.
Scientists think there are 300 million habitable planets in the Milky Way, and some may be home to intelligent life.
This year, two groups of astronomers plan to send messages containing information about humans and the location of Earth toward parts of space they think may be home to intelligent life.
The Hubble Space Telescope was born from a previous decadal survey. What leaps forward will come from this one?
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Some stars travel at high speeds through the universe and sometimes leave spectacular clouds of dust and gas in their wake.

Hypervelocity stars were discovered only 15 years ago and are the closest things in existence to real shooting stars. They travel at millions of miles per hour, so fast that they can escape from galaxies.
Flouride is created by Wolf–Rayet stars, here seen in the Milky Way by the Hubble Space Telescope.
Tracing the cosmic origin of toothpaste, scientists got a glimpse into the surprising chemistry of early galaxies.
A telescope in the outer solar system would be able to do unique science that is impossible closer to the Sun.
Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.
It can stretch your mind to ponder what’s really out there.
