Rough Cosmic Waters: Chandra X-ray Observatory Reveals “Turbulent” Effect of Black Holes

From NASA: “Chandra observations of the Perseus and Virgo galaxy clusters suggest turbulence may be preventing hot gas there from cooling, addressing a long-standing question of galaxy clusters do not form large numbers of stars.” Image Credit: NASA/CXC/Stanford/I. Zhuravleva et al

This week, NASA announced that the Chandra X-ray Observatory, now in its 15th [...]

The Case of the Exocomets Around Beta Pictoris

An artist’s impression showing exocomets orbiting the star Beta Pictoris. After analyzing archival observations that had been made with the HARPS spectrograph at ESO’s La Silla Observatory in Chile, astronomers have discovered two families of exocomets around this nearby young star.

Hubble Reveals Three Potential Deep Space Objects for New Horizons to Explore After Pluto

An artist’s impression of a Kuiper Belt object (KBO), located on the outer rim of our Solar System at a staggering distance of 4 billion miles from the Sun. A HST survey uncovered three KBOs that are potentially reachable by NASA’s New Horizons spacecraft after it passes by Pluto in mid-2015Image Credit: NASA, ESA, [...]

New Moon: LRO Discovers Evidence of Young Lunar Volcanism

A series of surface features called irregular mare patches that have been recently discovered on the Moon, are thought to be remnants of small basaltic eruptions that are indicative of lunar volcanic activity as recent as several million years ago. This image by the Lunar Reconnaissance Orbiter shows one such feature, called Maskelyne. Image [...]

NASA's NuSTAR Telescope Discovers 'Impossible' Ultra-Luminous Pulsar

NASA’s NuSTAR telescope recently discovered an ultra-luminous X-ray source (shown in the pink area in the circle) inside the nearby galaxy M82. This newly-discovered X-ray source was found to be powered by an extremely luminous pulsar, which produces the energy equivalent of 10 million Suns. Image Credit: NASA/JPL-Caltech

One week from today, NASA’s Red Planet armada is primed and ready with front row seats for the once-in-a-lifetime opportunity to study an Oort cloud comet, as it makes [...]

New Study Points to Alternative Origin for the 'Man in the Moon'

Oceanus Procellarum, or Ocean of Storms, an expansive flat basaltic basin that covers approximately 17 percent of the Moon’s near side, is surrounded by a series of linear gravitational anomalies (shown in red), as revealed by NASA’s GRAIL spacecraft. These anomalies indicate that the large basin was formed by volcanic processes rather than an [...]

Most of the Water In the Solar System Is Older Than the Sun, New Study Suggests

An artist’s concept of the formation process of the Solar System out of an interstellar molecular cloud and its enrichment with water. A recent study has indicated that up to half of Earth’s water is older than the Sun itself, likely originating in that cold molecular cloud that spawned our Solar System. Image credit: [...]

Clear Skies Above: Astronomers Detect Water Vapor on Cloud-Free Atmosphere of a Hot-Neptune

Sunny and hot all year-round, with no clouds on the horizon … That’s not a weather forecast only for the Maldive [...]

Hunting In the Dark: New Results Come From Alpha Magnetic Spectrometer on ISS, But No Definite Signs of Dark Matter Yet

The Alpha Magnetic Spectrometer is seen here at center left, following its installation on the S3 Truss on the International Space Station by the crew of the STS-134 space shuttle mission in 2011. The orbiting particle detector has been continuously collecting data ever since, on high-energy cosmic rays. Image Credit: NASA
