NASA’s Chandra Unveils Mysterious X-Ray Objects

Using NASA’s Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike any they have seen before. Astronomers suggest these newly spotted objects in other galaxies may help solve not one, but two long-standing questions in astrophysics. These mysterious objects give off unusually low-energy X-rays but intense levels of ultraviolet radiation. This […]

A photon from the biggest cosmic explosion since the Big Bang appears to have defied Einstein. Scientists may finally know how

A photon from the biggest cosmic explosion since the Big Bang, the gamma-ray burst nicknamed “the BOAT,” should not have reached Earth, according to Einstein. Now scientists may know how it did.

NASA’s Hubble, Webb Find Far-out Solar System Objects ‘Remember’ Past
NASA’s Hubble, Webb Find Far-out Solar System Objects ‘Remember’ Past

For the first time, scientists used the joint power of NASA’s Hubble and James Webb Space Telescopes to study some of the most far-flung bodies in our solar system, Trans-Neptunian Objects (TNOs). Some of these are the smallest and faintest ever directly seen. The researchers unexpectedly found fewer small TNOs than they expected, and that […]

NASA’s Dark Universe-Seeking Nancy Grace Roman Space Telescope Launches

Now on a three-month, million-mile journey to its final orbit, NASA’s Nancy Grace Roman Space Telescope will soon reveal the universe’s darkest secrets. The mission launched at 7:26 a.m. EDT Sunday aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Roman pairs a large field of […]

NASA’s Pandora Mission Begins Study of Exoplanets, Host Stars
NASA’s Pandora Mission Begins Study of Exoplanets, Host Stars

Pandora, NASA’s newest exoplanet mission and the first satellite to launch through the agency’s Astrophysics Pioneers program, is now making unique observations of worlds beyond our solar system and the stars they orbit. The mission will determine the atmospheric make-up of at least 20 exoplanets, including the presence of hazes, clouds, and water. “Pandora’s data […]

Galactic Gems Glisten in New Gallery From NASA’s Chandra
Galactic Gems Glisten in New Gallery From NASA’s Chandra

Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA’s Chandra X-ray Observatory and other telescopes displays a collection of galactic images that showcase this variety. Astronomers put galaxies into three main categories: spirals like our own Milky Way with arms emanating […]

Hubble Solves Merger Mystery From Milky Way’s Early Years

New Hubble data shows definitive evidence of a dwarf galaxy merging with the young Milky Way in the earliest phases of its evolution.

Lion Nebula Roars to Life With NASA’s Webb
Lion Nebula Roars to Life With NASA’s Webb

Observing across the starry “plains” of space, NASA’s James Webb Space Telescope has taken new images of NGC 2392, nicknamed the Lion Nebula. NASA’s Hubble Space Telescope previously viewed this planetary nebula in 2000, imaging the lion face-shaped target in visible light and revealing features such as the “mane” of hazy, comet-shaped objects. Now Webb […]
