Here are our picks for the most amazing space photos of the week.
Nineteen newly discovered dwarf galaxies seem to be missing their dark matter, and physicists aren't sure why.
For the first time ever, astronomers have spotted evidence of a planet circling a superdense stellar corpse known as a white dwarf, a new study reports.
Hoag's object, which is a galaxy within a galaxy within a galaxy, has befuddled stargazers since astronomer Arthur Hoag discovered it in 1950.
In a quiet orbit around the far side of the moon, three radio antennas are now outstretched, craning for whispers from a mysterious period early in the universe's history.
While black holes are famously known for devouring any matter that gets too close, these cosmic behemoths may have a nurturing side, too.
In 1987, a star exploded, creating the brightest supernova to light up Earth's skies in 400 years. That star's corpse has been missing for 30 years. Now, researchers think they've found it.
An international team of scientists has created the most detailed large-scale model of the universe to date, a simulation they call TNG50.
Gamma-ray bursts, the most powerful kinds of explosions known in the universe, can generate even more energetic light beams than astronomers previously realized, according to a set of new studies.
This week, the variable star Mira reaches its highest point, roughly halfway up in the southern sky at around 10 p.m. local time.
An intervening cluster of galaxies acts like a cosmic microscope and bends and magnifies light from a distant galaxy.
As humankind's ancestors were learning to walk upright, a star was launched from the supermassive black hole at the center of our galaxy at a staggering 3.7 million mph (6 million km/h).
SpaceX is planning to launch the second installment of its Starlink megaconstellation on Monday (Nov. 11), and astronomers are waiting to see — well, precisely what they will see.
The brightest X-ray burst ever observed by NICER released as much energy in 20 seconds as our sun does in about 10 days.
NASA has shared a trio of templates so you can carve your very own James Webb Space Telescope-themed pumpkin this Halloween.
Physicists have figured out what's lurking inside of white dwarfs, revealing the stellar corpses are creamy and filled with exotic quantum liquids.
A ghastly face with glowing eyes glares in deep space in a new image from the Hubble Space Telescope.
NASA's James Webb Space Telescope has passed a major milestone with a successful test of the spacecraft's sun shield.
