NASA Research To Be Featured at American Astronomical Society Meeting

From new perspectives on the early universe to illuminating the extreme environment near a black hole, discoveries from NASA missions will be highlighted at the 245th meeting of the American Astronomical Society (AAS). The meeting will take place Jan. 12-16 at the Gaylord National Resort & Convention Center in National Harbor, Maryland.

Hubble Rings In the New Year

This NASA/ESA Hubble Space Telescope image reveals a tiny patch of sky in the constellation Hydra. The stars and galaxies depicted here span a mind-bending range of distances. The objects in this image that are nearest to us are stars within our own Milky Way galaxy. You can easily spot these stars by their diffraction […]

Very Cold Detectors Reveal the Very Hot Universe and Kick Off a New Era in X-ray Astronomy

X-rays are radiated by matter hotter than one million Kelvin, and high-resolution X-ray spectroscopy can tell us about the composition of the matter and how fast and in what direction it is moving. Quantum calorimeters are opening this new window on the Universe.

Hubble Images a Grand Spiral

This NASA/ESA Hubble Space Telescope image features the glorious spiral galaxy NGC 5643, which is located roughly 40 million light-years away in the constellation Lupus, the Wolf. NGC 5643 is a grand design spiral, which refers to the galaxy’s symmetrical form with two large, winding spiral arms that are clearly visible.

NASA Scientific Balloon Flights to Lift Off From Antarctica

NASA’s Scientific Balloon Program has returned to Antarctica’s icy expanse to kick off the annual Antarctic Long-Duration Balloon Campaign, where two balloon flights will carry a total of nine missions to near space. Launch operations will begin mid-December from the agency’s Long Duration Balloon camp located near the U.S.

NASA’s Hubble Takes the Closest-Ever Look at a Quasar

Astronomers have used the unique capabilities of NASA’s Hubble Space Telescope to peer closer than ever into the throat of an energetic monster black hole powering a quasar. A quasar is a galactic center that glows brightly as the black hole consumes material in its immediate surroundings. The new Hubble views of the environment around […]

NASA’s Hubble Finds Sizzling Details About Young Star FU Orionis

In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our Sun. Unlike an exploding star though, it has declined in luminosity only languidly since then. […]

Hubble Takes a Look at Tangled Galaxies

This NASA/ESA Hubble Space Telescope image depicts the cosmic tangle that is MCG+05-31-045, a pair of interacting galaxies located 390 million light-years away and a part of the Coma galaxy cluster. The Coma Cluster is a particularly rich cluster that contains over a thousand known galaxies.

NASA’s Hubble Sees Aftermath of Galaxy’s Scrape with Milky Way

A story of survival is unfolding at the outer reaches of our galaxy, and NASA’s Hubble Space Telescope is witnessing the saga. The Large Magellanic Cloud, also called the LMC, is one of the Milky Way galaxy’s nearest neighbors. This dwarf galaxy looms large on the southern nighttime sky at 20 times the apparent diameter […]

Buckle Up: NASA-Funded Study Explores Turbulence in Molecular Clouds

On an airplane, motions of the air on both small and large scales contribute to turbulence, which may result in a bumpy flight. Turbulence on a much larger scale is important to how stars form in giant molecular clouds that permeate the Milky Way. In a new NASA-funded study in the journal Science Advances, scientists […]
