The Hubble Space Telescope observes the most distant single star ever. The star, named Earendel by astronomers, is 28 billion light-years away. It is the farthest detection of a star, dating back 900 million years after the Big Bang. This discovery surpasses Hubble's record from 2018, when it discovered a star that existed when the universe was roughly four billion years old.

New data from the Atacama Large Millimeter Array and Hubble Space Telescope, published in the "Nature Astronomy" journal, suggests interstellar comet 2I-Borisov contains large amounts of carbon monoxide and hydrogen cyanide. The new findings suggest the object was formed in the cold outer region of its planetary system.

Scientists say that, using data from the Hubble Space Telescope, they have found evidence of a 300,000-year-long burst of radiation originating 3.5 million years ago from or near the center of our galaxy, erupting through both galactic poles, with effects on the Magellanic Stream, 200,000 light-years away.

Kepler-1625b, an exoplanet proposed in 2017 to be orbited by an exomoon, the first possible example of a moon orbiting a planet in another stellar system, is confirmed with observations from the Hubble Space Telescope.

A photograph from the Hubble Space Telescope reveals a companion star that survived the explosion of a supernova in galaxy NGC 7424. This brings strong evidence to a theory according to which Type IIb "stripped-envelope" supernovae are due to stellar companions capturing hydrogen from the progenitor star's envelope before its explosion.

NASA astronomers use the Hubble and Spitzer space telescopes in research implying that "hot Saturn" (high surface-atmosphere temperatures and gas giant-mass) exoplanet WASP-39b, located 700 light-years from Earth, has a large amount of water molecules in its atmosphere.

Scientists announce that the LIGO and VIRGO gravitational wave observatories detected for the first time gravitational waves from the merger of two neutron stars. The event coincided with a short gamma ray burst GRB 170817A detected by the Fermi Gamma-ray Space Telescope, leading to SSS17a, the immediate follow-up observations by the Hubble Space Telescope and numerous ground-based telescopes. This confirms the theory according to which neutron star mergers are the cause of at least some short gamma-ray bursts.
