The James Webb Space Telescope may have been touted a successor to Hubble, but the old-timer still has some life left in it. These two iconic instruments have now teamed up to take a deep-field image of the colorful “Christmas Tree galaxy cluster.”

Move over TRAPPIST-1 – there’s an exciting new planetary system in town. Meet Kepler-385, home to seven Super-Earths that were just discovered in existing data.

As spooky season wraps, NASA has a final Halloween treat. Using two X-ray telescopes, astronomers have visualized the ‘bones’ in one of space's most haunting phenomena, the pulsar wind nebula MSH 15-52, also known as the ‘cosmic hand' or 'hand of God'.

Astronomers have detected one of the most energetic explosions in the history of the universe: a gamma ray burst from a neutron star collision. For the first time ever, heavy metals were detected in the explosion, totaling hundreds of Earths in mass.

NASA’s anticipated Roman Space Telescope is taking shape, and will soon measure light from a billion galaxies, perform a microlensing survey deep in the Milky Way, monitor hundreds of millions of stars and peer into unseen galactic neighborhoods.

Cosmic radio signals are beaming to Earth every day – and astronomers are stumped as to their origin. Now a new study finds evidence that these signals, known as fast radio bursts (FRBs), could be caused by “starquakes.”

It feels like every time astronomers get a handle on a cosmic phenomenon, a new one pops up that sends them back to the drawing board. Case in point – Hubble has spotted a burst of light in a region of space where there didn’t seem to be a trigger.

The James Webb Space Telescope can look farther back in space and time than ever before – and it’s revealed puzzling galaxies that seem to be too advanced for their age. Now astronomers have proposed a new explanation for them – starburst galaxies.

Astronomers have discovered a new type of star, which could be key to solving a cosmic mystery. This massive helium star has an ultra-strong magnetic field, meaning it could be the preliminary stage of a magnetar, which so far has unknown origins.

The cosmos is full of surprises. Now astronomers have discovered a “heartbreak” star system where tidal waves, three times taller than the Sun, rise and crash on the surface of a giant star thanks to the motions of a smaller companion star.

Astronomers have discovered the cosmic equivalent of a parent crashing a teenagers’ party to make sure they have enough water. An aging star has been detected passing through a young star-forming region, delivering elements crucial for life to form.

Astronomers have detected a radio signal that blares for several minutes at a time, every 21 minutes, and has been doing so for at least 35 years. This bizarre signal doesn’t fit any known object without some major revisions to current physics.
