Comet Tsuchinshan-ATLAS is now visible in the early morning sky.

The SAGA Survey just published three new research articles that provide us with new insights into the uniqueness of our own Milky Way Galaxy after completing the census of 101 satellite systems similar to the Milky Way's.

The discovery of a 'weird' and unprecedented galaxy in the early Universe could 'help us understand how the cosmic story began', astronomers say. GS-NDG-9422 (9422) was found approximately one billion years after the Big Bang and stood out because it has an odd, never-before-seen light signature -- indicating that its gas is outshining its stars. The 'totally new phenomena' is significant, researchers say, because it could be the missing-link phase of galactic evolution between the Universe's first stars and familiar, well-established galaxies.

This dusty region is forming stars.

Astronomers have observed the atmosphere of a hot and uniquely inflated exoplanet using NASA's James Webb Space Telescope.

What will happen as this already bright comet approaches?

Observations confirm astronomers' expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam's exceptionally wide field of view and special filters played a crucial role in reaching this conclusion, and the observations reveal why previous studies seeking to characterize the density of early-Universe quasar neighborhoods have yielded conflicting results.

By staring into the hellish landscape of Jupiter's moon Io -- the most volcanically active location in the solar system -- astronomers have been able to study a fundamental process in planetary formation and evolution: tidal heating.

Researchers have developed a Martian atmospheric evolution model to propose a new theory about Mars's past.

A newly discovered cluster-scale strong gravitational lens, with a rare alignment of seven background lensed galaxies, provides a unique opportunity to study cosmology.

Astronomers have spotted the biggest pair of black hole jets ever seen, spanning 23 million light-years in total length. That's equivalent to lining up 140 Milky Way galaxies back to back.

Astronomers examined galaxy Arp 107 which has revealed a wealth of information about star-formation and how two galaxies collided hundreds of million years ago. Arp 107 is located 465 million light-years from Earth in the constellation Leo Minor.

Watching for changes in Mars' orbit over time could be new way to detect passing dark matter, according to researchers.

With the help of NASA's Hubble Space Telescope, an international team of scientists has found more black holes in the early universe than has previously been reported. The new result can help scientists understand how supermassive black holes were created.
