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 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 […]

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

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 […]

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. […]

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 […]

Russian Doll Galaxy Clusters Reveal Information About Dark Energy

Researchers are using a large sample of galaxy cluster to investigate dark energy, showing that dark energy has not changed over billions of years. Astronomers have used data from NASA’s Chandra X-ray Observatory, ESA’s Planck and a large list of optical telescopes to develop a powerful new method for investigating dark energy, the mysterious energy […]

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, […]

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 […]

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 […]

New Horizons Views Pluto’s ‘Halo’ Craters

This newly released image from the New Horizons Spacecraft looks within Pluto’s informally named Vega Terra region, showing a field of eye-catching craters that looks like a cluster of bright halos scattered across a dark landscape. The region is far west of the hemisphere NASA’s New Horizons spacecraft viewed during close approach last summer. The […]

Hubble Views a Star ‘Inflating’ a Giant Bubble

Just in time for the 26th anniversary of Hubble’s launch on April 24, 1990, the telescope has photographed an enormous, balloon-like bubble being blown into space by a super-hot, massive star. Astronomers trained the iconic telescope on this colorful feature, called the Bubble Nebula, or NGC 7635. “As Hubble makes its 26th revolution around our […]

Astronomers Find Lone Planetary-Mass Object in Family of Stars

New data from WISE and its predecessor, the Two Micron All Sky Survey, reveals the lowest-mass free-floating object in TW Hydrae family — a likely brown dwarf called WISEA J114724.10−204021.3. In 2011, astronomers announced that our galaxy is likely teeming with free-floating planets. In fact, these lonely worlds, which sit quietly in the darkness of […]

Fermi Telescope Poised to Pin Down Gravitational Wave Sources

Fermi observations are helping researchers gain a much deeper understanding of gravitational waves. On September 14, waves of energy traveling for more than a billion years gently rattled space-time in the vicinity of Earth. The disturbance, produced by a pair of merging black holes, was captured by the Laser Interferometer Gravitational-Wave Observatory (LIGO) facilities in […]

Hubble Views NGC 4111

This newly released Hubble image shows lenticular galaxy NGC 4111. The elegant simplicity of NGC 4111, seen here in this image from the NASA/ESA Hubble Space Telescope, hides a more violent history than you might think. NGC 4111 is a lenticular, or lens-shaped, galaxy, lying about 50 million light-years from us in the constellation of […]

New Research Shows Pluto’s Haze Varies in Brightness

New images from NASA’s New Horizons Spacecraft reveal that Pluto’s haze varies in brightness. Scientists on NASA’s New Horizons mission team are learning more about the structure and behavior of Pluto’s complex atmosphere by discovering new attributes of its extensive haze layers. The hazes were first discovered by New Horizons in July, as the spacecraft […]

Cassini Spacecraft Views Enceladus' South Pole

NASA’s Cassini Spacecraft views a Y-shaped discontinuity on Enceladus’ south pole. A sinuous feature snakes northward from Enceladus’ south pole like a giant tentacle. This feature, which stretches from the terminator near center, toward upper left, is actually tectonic in nature, created by stresses in Enceladus’ icy shell. Geologists call features like these on Enceladus […]
