VISTA Reveals Hidden Secrets of Orion’s Clouds

The VISTA infrared survey telescope reveals the most detailed view of Orion A molecular cloud in the near-infrared. The new image from the VISION survey (VIenna Survey In Orion) is a montage of images taken in the near-infrared part of the spectrum by the VISTA survey telescope at ESO’s Paranal Observatory in Chile. It covers […]

Juno Image Shows Jupiter with the Great Red Spot

Using data from Juno’s JunoCam instrument, citizen scientist Roman Tkachenko created this image of a crescent Jupiter and the iconic Great Red Spot. The image also shows a series of storms shaped like white ovals, known informally as the ‘string of pearls.’ Below the Great Red Spot a reddish long-lived storm known as Oval BA […]

Hubble Views a Slice of Sagittarius

This Hubble image of the week shows part of the sky in the constellation of Sagittarius (The Archer). The region is rendered in exquisite detail — deep red and bright blue stars are scattered across the frame, set against a background of thousands of more distant stars and galaxies. Two features are particularly striking: the […]

Astronomers Discover Powerful Cosmic Double Whammy

Using data from NASA’s Chandra X-ray Observatory and several other telescopes, a team of astronomers has discovered a cosmic one-two punch unlike any ever seen before. The phenomena occurred in a pair of colliding galaxy clusters called Abell 3411 and Abell 3412. This result shows that an eruption from a supermassive black hole combined with […]

Cassini Finds Monstrous Ice Cloud in Titan’s South Polar Region

On January 14, 2005, ESA’s Huygens probe made its descent to the surface of Saturn’s hazy moon, Titan. Carried to Saturn by NASA’s Cassini spacecraft, Huygens made the most distant landing ever on another world, and the only landing on a body in the outer solar system. This video uses actual images taken by the […]

Photons Struggle to Escape Distant Galaxies

Using the Isaac Newton Telescope, a team of astronomers has discovered giant halos of photons around early Milky Way type galaxies. In order to understand how our own Milky Way galaxy formed and evolved, astronomers rely on observing distant galaxies. As their light takes billions of years to reach us, telescopes can be used as […]

Study Shows the Moon is Older Than Prevoiusly Thought

By analyzing minerals brought back by the 1971 Apollo mission, a new study from UCLA shows that the moon is 40 million to 140 million years older than scientists previously thought. A UCLA-led research team reports that the moon is at least 4.51 billion years old, or 40 million to 140 million years older than […]

Galaxy of a Fast Radio Burst Identified

For the first time, a team of astronomers has pinpointed the location of a “fast radio burst” and have used this to identify its home galaxy. The galaxy, located over 3 billion light years away, is small, a so-called dwarf galaxy, and very different to our own Milky Way. Also, a persistent, compact radio source […]

Farthest Stars in Milky Way Might Be Ripped from Another Galaxy

New research reveals that five of the 11 farthest known stars in our galaxy were ripped from another galaxy – the Sagittarius dwarf. The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth, well outside the Milky Way’s spiral disk. New research by Harvard astronomers shows that half of those […]

Hubble Reveals Exocomets Plunging into a Young Star

The Hubble Space Telescope has discovered comets plunging into young star HD 172555, which resides 95 light-years from Earth. The exocomets — comets outside our solar system — were not directly seen around the star, but their presence was inferred by detecting gas that is likely the vaporized remnants of their icy nuclei. HD 172555 […]

New Cassini Image of Mimas' Mountain

This newly released Cassini image shows Herschel Crater on Saturn’s Moon Mimas, revealing an indication of the size of the crater’s towering walls and central peak. Named after the icy moon’s discoverer, astronomer William Herschel, the crater stretches 86 miles (139 kilometers) wide — almost one-third of the diameter of Mimas (246 miles or 396 […]

Molecular Outflows in Local ULIRGs

A new study from the Harvard-Smithsonian Center for Astrophysics finds that ultra-luminous galaxies can expel as much as a thousand solar-masses per year. Galaxies evolve over billions of years in part through the activity of star formation and their supermassive nuclear black holes, and also by mergers with other galaxies. Some features of galaxies, in […]

Hubble Views 'Shadow Play' Caused by Possible Planet

A team of astronomers view a shadow sweeping around a gas-and-dust disk encircling the young star TW Hydrae. Searching for planets around other stars is a tricky business. They’re so small and faint that it’s hard to spot them. But a possible planet in a nearby stellar system may be betraying its presence in a […]

NASA Selects Mission to Study Black Holes, Cosmic X-ray Mysteries

A new NASA mission will allow astronomers to explore the hidden details of some of the most extreme and exotic astronomical objects, such as stellar and supermassive black holes, neutron stars and pulsars. Objects such as black holes can heat surrounding gases to more than a million degrees. The high-energy X-ray radiation from this gas […]

Scientists Offer Sharper Insight into Pluto’s Bladed Terrain

A team of researchers used a model similar to what meteorologists use to forecast weather and a computer simulation of the physics of evaporating ices to find evidence of snow and ice features on Pluto. Formed by erosion, the features, known as “penitentes,” are bowl-shaped depressions with blade-like spires around the edge that rise several […]
