'Planet Hunters' Citizen Scientists Discover Distant Exoplanet With Time-Keeping Issues

After analyzing many millions of light curves that were obtained by NASA’s Kepler space telescope, a team of volunteers from the ‘Planet Hunters’ citizen science project, have discovered a distant exoplanet,named PH3c, which exhibits a highly irregular orbital period around its host star.

Punctuality is considered one of the basic cultural […]

Hubble Observes the 'Ghost Light' of Orphaned Stars Inside Galaxy Cluster

The massive galaxy cluster Abell 2744 takes on a ghostly look in this view by the Hubble Space Telescope, where the total starlight from the cluster has been artificially colored blue. This reveals that not all the starlight is contained within the galaxies, which appear as bright blue-white blobs in the image. A fraction […]

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

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: […]
