Interstellar comet 3I/ATLAS contains 30X more semi-heavy water than comets in our solar system, indicating that its system of origin formed under conditions far colder than our own

Astronomers Reveal First Image of the Black Hole at the Heart of Our Galaxy

Astronomers have discovered the most distant quasar yet found — a cosmic monster more than 13 billion light-years from Earth powered by a supermassive black hole more than 1.6 billion times more massive than the Sun and more than 1,000 times brighter than our entire Milky Way Galaxy.

Astronomers have made the first-ever observations of a circumplanetary disk, the planet-girding belt of dust and gas that astronomers strongly theorize controls the formation of planets and gives rise to an entire system of moons.

Powerful flare from star Proxima Centauri detected with ALMA

Astronomers may be close to solving a 30-year-old mystery: identifying the source of a faint infrared glow that permeates the Milky Way and other galaxies

Astronomers have detected traces of methyl chloride, or Freon-40, surrounding infant stars and the comet 67P/Churyumov-Gerasimenko, suggesting it forms naturally in interstellar clouds
