New Horizons Reveals a Distinct Water-Ice Signature on the Surface of Hydra

New Horizons Reveals Water-Ice Signature on the Surface of Hydra

NASA’s New Horizons Spacecraft reveals a distinct water-ice signature on the surface of Pluto’s outermost moon, Hydra. NASA’s New Horizons spacecraft has sent home the first compositional data about Pluto’s four small satellites. The new data show the surface of Hydra, Pluto’s outermost small moon, is dominated by nearly pristine water ice – confirming hints […]

Astronomers Examine the Processes Involved in Generating Turbulence

Astronomers Examine the Physical Processes Involved in Generating Turbulence

A new study of turbulence in galaxies concludes that in many cases it is generated not by star formation but by gravitational effects alone. The gas in galaxies is typically seen to be moving at very rapid, even supersonic velocities, providing clear evidence that the medium is highly turbulent. Looking more closely at gas clouds […]

New Research May Help in the Development of Nano-Optical Transistors for a Photonic Computer

A Step Towards the Photonic Computer

Researchers show that a single molecule allows a beam of light with a few photons to be controlled – a step towards the photonic computer. The Jedi knights of the Star Wars saga are engaged in an impossible fight. This does not result from the superiority of the enemy empire, but from physics because laser […]

Yale Researchers Identify a Genetic Mutation Linked to Acne

Yale Study Zeroes in on Mutation Linked to Zits

New research from Yale University has identified a genetic mutation responsible for the defects that give rise to mild and severe acne, possibly revealing new targets for acne treatment. In the study, the Yale-led team took blood and tissue samples from three individuals with a rare form of acne known as nevus comedonicus. By sequencing […]

Astronomers Discover Three Potentially Habitable Worlds

Three Potentially Habitable Worlds Found Around Nearby Ultracool Dwarf Star TRAPPIST-1

Astronomers have discovered three planets with sizes and temperatures similar to those of Venus and Earth, orbiting an ultra-cool dwarf star just 40 light-years from Earth. Astronomers using the TRAPPIST telescope at ESO’s La Silla Observatory have discovered three planets orbiting an ultracool dwarf star just 40 light-years from Earth. These worlds have sizes and […]

Mars Reconnaissance Orbiter Reveals Clues about Volcanoes Under Ice on Ancient Mars

Clues about Volcanoes Under Ice on Ancient Mars Revealed

New evidence from NASA’s Mars Reconnaissance Orbiter suggests that volcanoes erupted beneath an ice sheet on Mars billions of years ago. The research about these volcanoes helps show there was extensive ice on ancient Mars. It also adds information about an environment combining heat and moisture, which could have provided favorable conditions for microbial life. […]

Evidence Points to Planet Nine Existing, But How Was it Produced?

Update on Planet Nine

New research examines Planet Nine and the mystery behind its existence. Earlier this year scientists presented evidence for Planet Nine, a Neptune-mass planet in an elliptical orbit 10 times farther from our Sun than Pluto. Since then theorists have puzzled over how this planet could end up in such a distant orbit. New research by […]

Yale Engineers Develop a New Tool to Fight Dust

Yale Develops a New Tool in the War Against Dust

Inspired by gecko feet, Yale researchers have developed a promising tool in the war on dust. Micrometric and sub-micrometric contaminant particles — what most of us call “dust” — can cause big problems for art conservators, the electronics industry, aerospace engineers, and others. These nanoparticles can prevent a cellphone from working or rob the vitality […]

Newly Released Cassini Image – The Dew Drop of Saturn

New Cassini Image Dew Drop of Saturn

This newly released image of Saturn and Enceladus was taken by NASA’s Cassini Spacecraft last May. The water-world Enceladus appears here to sit atop Saturn’s rings like a drop of dew upon a leaf. Even though it appears like a tiny drop before the might of the giant Saturn, Enceladus reminds us that even small […]

New Elevation Map of Pluto’s ‘Heart’ from New Horizons

New Elevation Map of Pluto from New Horizons

NASA releases a new elevation map of Pluto’s heart-shaped surface area. This newest shaded relief view of the region surrounding the left side of Pluto’s heart-shaped feature – informally named Sputnik Planum – shows that the vast expanse of the icy surface is on average 2 miles (3 kilometers) lower than the surrounding terrain. Angular […]

Hubble Image of the Week – NGC 4394

New Hubble Image of NGC 4394

This newly released Hubble images shows NGC 4394, which is located about 55 million light-years away. Discovered in 1784 by the German–British astronomer William Herschel, NGC 4394 is a barred spiral galaxy situated about 55 million light-years from Earth. The galaxy lies in the constellation of Coma Berenices (Berenice’s Hair), and is considered to be […]

Hubble Views Galaxy UGC 477

Hubble Views Galaxy UGC 477

This newly released Hubble image shows galaxy UGC 477, which is located just over 110 million light-years away in the constellation of Pisces (The Fish). UGC 477 is a low surface brightness (LSB) galaxy. First proposed in 1976 by Mike Disney, the existence of LSB galaxies was confirmed only in 1986 with the discovery of […]

Astronomers Develop New Method to Determine Oxygen Abundance in Stars

New Models Determine the Oxygen Abundance in Giant Stars

Astronomers from the Harvard-Smithsonian Center for Astrophysics have developed a new computational method to determine the abundance of oxygen in these and similar stars, and in particular in giant stars. The code finds values that are more self-consistent than previous estimates. Oxygen is the third most abundant element in the universe, after hydrogen and helium. […]

Fermi Helps Link Cosmic Neutrino to Blazar Blast

NASA's Fermi Helps Link Cosmic Neutrino to Blazar Blast

Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Light from this blast began arriving at Earth in 2012. Now astronomers using data from NASA’s Fermi Gamma-ray Space Telescope have shown that a record-breaking neutrino seen around the same time likely was […]

Astronomers Discover Moon Orbiting the Dwarf Planet Makemake

Hubble Space Telescope Discovers Moon Orbiting the Dwarf Planet Makemake

Using the Hubble Space Telescope a team of astronomers just discovered a moon orbiting dwarf planet Makemake — the third largest known object past the orbit of Neptune, about two thirds the size of Pluto. Peering to the outskirts of our solar system, NASA’s Hubble Space Telescope has spotted a small, dark moon orbiting Makemake, […]

Astronomers Use Light Echoes to Measure Protoplanetary Disk

Spitzer Uses Light Echoes to Give Clues to Protoplanetary Disk

Using data from NASA’s Spitzer Space Telescope and four ground-based telescopes, astronomers determine the distance from a star to the inner rim of its surrounding protoplanetary disk. Imagine you want to measure the size of a room, but it’s completely dark. If you shout, you can tell if the space you’re in is relatively big […]

Astronomers Gain a Better Understanding of Spica

Stellar Modelling of Spica

A newly published study details Spica, an eccentric double-lined spectroscopic binary system with a β Cep type variable primary component. The familiar star Spica (Alpha Virginis) is the fifteenth brightest star in the night sky, in part because it is relatively nearby, only about 250 light-years away. It is easy to find by following the […]
