Want to take a trip to the center of the Milky Way? Check out a new immersive, ultra-high-definition visualization.

Just as high-definition imaging is transforming home entertainment, it is also advancing how astronomers study the universe.

The center of our galaxy is a frenzy of activity. A behemoth black hole -- 4 million times as massive as the Sun -- blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and subsequently explode.

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have found a pulsar speeding away from its presumed birthplace at nearly 700 miles per second, with its trail pointing directly back at the center of a shell of debris from the supernova explosion that created it

The Origin Of Heavy Elements

A research team of experts in atomic physics, nuclear fusion science, and astronomy succeeded in computing millions of highly accurate atomic data of neodymium ions in the Japan-Lithuania international collaboration.

The Cigar Galaxy (also known as M82) is famous for its extraordinary speed in making new stars, with stars being born 10 times faster than in the Milky Way.

Old Stars Live Longer Than We Thought

Towards the end of their lives some 95% of stars evolve into red giants which lose their mass via a "stellar wind". Eventually they end up as planetary nebulae, ionized gas with a central hot star, a white dwarf.

Astronomers have spent decades looking for something that sounds like it would be hard to miss: about a third of the "normal" matter in the Universe. New results from NASA's Chandra X-ray Observatory may have helped them locate this elusive expanse of missing matter.

A compilation of scientific results from The Stratospheric Observatory for Infrared Astronomy, SOFIA, reveal new clues to how stars form and galaxies evolve, and closer to understanding the environment of Europa and its subsurface ocean.

Hubble Peers into the Vast Distance

This picture showcases a gravitational lensing system called SDSS J0928+2031. Astronomers are using NASA/ESA Hubble Space Telescope observations of this type of lensing to research how stars form and evolve in distant galaxies.

In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material.

An international team of more than 200 astronomers from 18 countries has published the first phase of a major new radio sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope.

A volunteer working with the NASA-led Backyard Worlds: Planet 9 project has found the oldest and coldest known white dwarf -- an Earth-sized remnant of a Sun-like star that has died -- ringed by dust and debris. Astronomers suspect this could be the first known white dwarf with multiple dust rings.

In this image, the NASA/ESA Hubble Space Telescope has captured the smoking gun of a newborn star, the Herbig-Haro objects numbered 7 to 11 (HH 7-11).

ESA's Gaia satellite has looked beyond our galaxy and explored two nearby galaxies to reveal the stellar motions within them and how they will one day interact and collide with the Milky Way -- with surprising results.

Bubbles Of Brand New Stars

This region of the Large Magellanic Cloud (LMC) glows in striking colours in this image captured by the Multi Unit Spectroscopic Explorer (MUSE) instrument on ESO's Very Large Telescope (VLT).

Scientists have charted the environment surrounding a stellar-mass 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 Station.

The Space Telescope Science Institute (STScI) in Baltimore, Maryland, in conjunction with the University of Hawaii Institute for Astronomy (IfA), is releasing the second edition of data from Pan-STARRS -- the Panoramic Survey Telescope & Rapid Response System -- the world's largest digital sky survey.

Investigating the history of our cosmos with a large sample of distant 'active' galaxies observed by ESA's XMM-Newton, a team of astronomers found there might be more to the early expansion of the Universe than predicted by the standard model of cosmology.

A new telescope will take a sequence of hi-res snapshots with the world's largest digital camera, covering the entire visible night sky every few days -- and repeating the process for an entire decade.
