The star-mapping satellite Gaia has found more than 20 stars speeding across the Milky Way toward intergalactic space. There are just a few things that can slingshot a star out of a galaxy and all of them take some extreme gravitational...

We can now map the interiors of stars by "listening" to their harmonies as they vibrate with seismic waves.

Humans have been studying the stars for thousands of years, but astrophysicist Juna Kollmeier is on a special mission: creating the most detailed 3-D maps of the universe ever made. Journey across the cosmos as she shares her team's work...

On May 29, 1919, a total solar eclipse helped to prove Albert Einstein's theory of general relativity. Einstein's theory suggested that gravity could bend light by curving the fabric of spacetime. To prove it, he thought it would be a...

With star names like 2MASS J05551028+0724255, it might seem like astronomers are not so great at naming things. But if you know the code, these names can actually help you find the star in the sky.

On schedule to launch no later than May 2027, NASA’s Nancy Grace Roman Space Telescope mission will help uncover some of the biggest mysteries in the cosmos. The state-of-the-art telescope on the Roman spacecraft...

Considering how massive our universe is, we know the distances to cosmic objects surprisingly well. What tools and clues do scientists use to measure distances that are so enormous they sound like made-up numbers?

Sometimes, ancient ruins can be a little out of the way, but with some creativity, we can use satellites for those hard to reach areas.

Scientists have reached a new frontier in our understanding of pulsars, the dense, whirling remains of exploded stars, thanks to observations from NASA’s Neutron star Interior Composition Explorer (NICER). Data...

In order to know how the universe will end, we must know what has happened to it so far. This is just one mystery NASA's forthcoming Nancy Grace Roman Space Telescope mission will tackle as it explores the distant...

Astronomers have found a Hot Jupiter - WASP-121b - that is leaking metal, and put together a new 3D map of the Milky Way showing that our galaxy is actually a bit twisted!

Scientists have thought for awhile that pulsars could be used as a sort of galactic positioning system, and astronomers have published the most advanced topographical map of Titan to date!

Create a boosted tree model to classify stars based on important characteristics.

Scientists have mapped the environment surrounding a black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space...

NASA officially is beginning work on an astrophysics mission designed to help unlock the secrets of the universe -- the Wide Field Infrared Survey Telescope (WFIRST).



With a view 100 times bigger than that of...

On schedule to launch in the mid-2020s, NASA’s Wide Field Infrared Survey Telescope (WFIRST) mission will help uncover some of the biggest mysteries in the cosmos. The state-of-the-art telescope on the...

On June 11, NASA's Fermi Gamma-ray Space Telescope celebrates a decade of using gamma rays, the highest-energy form of light in the cosmos, to study black holes, neutron stars, and other extreme cosmic objects and...

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered 21 planets outside our solar system and captured data on other interesting events occurring in the southern sky during its first year of...

In the mid-1800s, mariners sailing the southern seas navigated at night by a brilliant star in the constellation Carina. The star, named Eta Carinae, was the second brightest star in the sky for more than a decade....

In this Hubble image, a super-hot, massive star is blowing an enormous bubble into space. Fittingly named the Bubble Nebula, this beautiful cosmic object is roughly seven light-years across and resides 7,100 light-years from...

This spectacular Hubble image of the Butterfly Nebula shows a colorful view of star death. The "wings" of the butterfly are regions of gas heated to more than 36,000° F (about 20,000° C) that are tearing across space at more than...

Familiar stars shine, nebulae glow, and nearby galaxies tantalize in a new panorama of the northern sky assembled from 208 images from NASA’s Transiting Exoplanet Survey Satellite (TESS).



Within this starry...

Observations of Jupiter's icy moon Europa from NASA's Hubble Space Telescope have revealed the presence of persistent water vapor — but, mysteriously, only in one hemisphere.



Europa harbors a vast ocean underneath...

Hubble has seen galaxies at the edge of the visible universe. It has unlocked a cosmos so vast and filled with wonder that it boggles the mind. The Hubble Telescope has learned how galaxies merge, and found the powerful...
