Hubble weighs in on mass of three million billion suns

Tue, 16 Jan 2018 13:22:53 EST

In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns—so it's little wonder that it has earned the nickname of "El Gordo" ("the Fat One" in Spanish)! Known officially as ACT-CLJ0102-4915, it is the largest, hottest, and brightest X-ray galaxy cluster ever discovered in the distant Universe.

Astronomers conduct detailed chemical analysis of eleven globular clusters

Tue, 16 Jan 2018 09:10:09 EST

GeoCarb—a new view of carbon over the Americas

Fri, 12 Jan 2018 07:50:52 EST

A new NASA Earth science mission in the early stages of design may achieve a transformational advance in our understanding of the global carbon cycle by mapping concentrations of key carbon gases from a new vantage point: geostationary orbit. Satellites in geostationary orbit travel at the same speed as Earth's rotation, allowing them to remain over the same place on Earth's surface at all times.

The mystery surrounding the fate of a secret military satellite deepened Thursday when the Pentagon refused to answer even simple questions about whether the mission to launch it had gone awry.

Hubble and Spitzer team up to find magnified and stretched out image of distant galaxy

Thu, 11 Jan 2018 15:22:20 EST

An intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the proverbial needle-in-a-haystack: the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing.

Hubble probes the archeology of our Milky Way's ancient hub

Thu, 11 Jan 2018 15:20:16 EST

For many years, astronomers had a simple view of our Milky Way's central hub, or bulge, as a quiescent place composed of old stars, the earliest homesteaders of our galaxy.

Steep slopes on Mars reveal structure of buried ice

Thu, 11 Jan 2018 15:08:21 EST

Researchers using NASA's Mars Reconnaissance Orbiter (MRO) have found eight sites where thick deposits of ice beneath Mars' surface are exposed in faces of eroding slopes.

A team led by CU Boulder researchers has caught a supermassive black hole in a distant galaxy snacking on gas and then "burping"—not once, but twice.

Magnetic coil springs accelerate particles on the Sun

Thu, 11 Jan 2018 14:47:45 EST

In April and July 2014, the Sun emitted three jets of energetic particles into space, that were quite exceptional: the particle flows contained such high amounts of iron and helium-3, a rare variety of helium, as have been observed only few times before. Since these extraordinary events occurred on the backside of our star, they were not discovered immediately. A group of researchers headed by the Max Planck Institute for Solar System Research (MPS) and the Institute for Astrophysics of the University of Göttingen (Germany) present a comprehensive analysis now in the Astrophysical Journal. It is based on data from the twin space probes STEREO A and STEREO B, which – at that time still both operating – were in a favorable observation position behind the Sun at the crucial time. For the first time, the study shows a correlation between helium-3 and iron-rich particle flows and helical eruptions of ultraviolet radiation in the Sun's atmosphere. These could provide the necessary energy to accelerate the particles into space.

Citizen scientists discover five-planet system

Thu, 11 Jan 2018 14:42:22 EST

In its search for exoplanets—planets outside of our solar system—NASA's Kepler telescope trails behind Earth, measuring the brightness of stars that may potentially host planets. The instrument identifies potential planets around other stars by looking for dips in the brightness of the stars that occur when planets cross in front of, or transit, them. Typically, computer programs flag the stars with these brightness dips, then astronomers look at each one and decide whether or not they truly could host a planet candidate.

Possible lava tube skylights discovered near the North Pole of the Moon

Thu, 11 Jan 2018 14:37:22 EST

The SETI Institute and the Mars Institute announced today the discovery of small pits in a large crater near the North Pole of the Moon, which may be entrances to an underground network of lava tubes. The pits were identified through analysis of imaging data from NASA's Lunar Reconnaissance Orbiter (LRO). If water ice is present, these potential lava tube entrances or "skylights" might allow future explorers easier access to subsurface ice, and therefore water, than if they had to excavate the gritty ice-rich "regolith" (surface rubble) at the actual lunar poles.

GBT detection unlocks exploration of 'aromatic' interstellar chemistry

Thu, 11 Jan 2018 14:34:39 EST

Astronomers had a mystery on their hands. No matter where they looked, from inside the Milky Way to distant galaxies, they observed a puzzling glow of infrared light. This faint cosmic light, which presents itself as a series of spikes in the infrared spectrum, had no easily identifiable source. It seemed unrelated to any recognizable cosmic feature, like giant interstellar clouds, star-forming regions, or supernova remnants. It was ubiquitous and a bit baffling.

No planets needed: NASA study shows disk patterns can self-generate

Thu, 11 Jan 2018 14:31:25 EST

When exoplanet scientists first spotted patterns in disks of dust and gas around young stars, they thought newly formed planets might be the cause. But a recent NASA study cautions that there may be another explanation—one that doesn't involve planets at all.

Hubble finds substellar objects in the Orion Nebula

Thu, 11 Jan 2018 14:29:23 EST

Using NASA's Hubble Space Telescope to peer deep into the vast stellar nursery called the Orion Nebula, astronomers searched for small, faint bodies. What they found was the largest population yet of brown dwarfs—objects that are more massive than planets but do not shine like stars. Researchers identified 17 brown dwarf companions to red dwarf stars, one brown dwarf pair, and one brown dwarf with a planetary companion. They also found three giant planets, including a binary system where two planets orbit each other in the absence of a parent star. This survey could only be done with Hubble's exceptional resolution and infrared sensitivity.
