Young stars in NGC 7822

NGC 7822 in Cepheus

Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away.  Image Credit Manuel Fernández Suarez

Mars Sand Dunes in Motion

Mars Sand Dunes

A rippled dune front in Herschel Crater on Mars moved an average of about two meters (about two yards) between March 3, 2007 and December 1, 2010, as seen in these images from NASA’s Mars Reconnaissance Orbiter. Note that the pattern of ripples on the dune surface has changed completely between the two images.  Image credit: NASA/JPL-Caltech/Univ. of Ariz./JHUAPL

Big Five and twilight arch

The photo above shows a gathering of planets and the waning crescent Moon as captured from Tivoli, Namibia in Africa, just before dawn on May 30, 2011. The “Big Five” in Africa refers to the top five big game animals; lion, leopard, rhinoceros, Cape buffalo, and elephant.  Photographer: Eduard von Bergen.

We’ ve been overlooked by advanced ET civilizations- Stephen Hawking

Life in the Universe

In his famous lecture, “Life in the Universe”, Stephen Hawking asks: “What are the chances that we will encounter some alien form of life, as we explore the galaxy?” If the argument about the time scale for the appearance of life on Earth is correct, Hawking says “there ought to be many other stars, whose planets have life on them.

November’s annular Eclipse

Annular Eclipse

On Friday, November 25, an annular eclipse will occur, reaching a maximum coverage at 06:20:17 UT of magnitude .905. It will be the largest – and last – partial eclipse of the year. But its visibility will be limited to the most southern latitudes… outside of the Antarctic continent, only New Zealand, Tasmania and parts of South Africa will have any visibility of the event.

Black Hole Birth announcement

black hole in Cygnus X-1

New details about the birth of a famous black hole that took place millions of years ago have been uncovered, thanks to a team of scientists who used data from NASA’s Chandra X-ray Observatory as well as from radio, optical and other X-ray telescopes.

Is there Life on icy Jupiter’s moon Europa?

surface of moon Europa

Data from a NASA planetary mission has provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter’s moon, Europa.

Saturn’s huge Northern Storm

Saturn Cassini spacecraft

This false-color mosaic from NASA’s Cassini spacecraft shows the tail of Saturn’s huge northern storm. In mid-September 2004, the Cassini spacecraft chronicled a similar, but smaller, storm in the southern hemisphere called the “Dragon Storm.”

New Map of the Moon

LRO Map of the Moon

NASA’s Lunar Reconnaissance Orbiter science team released the highest resolution near-global topographic map of the moon ever created. This new topographic map shows the surface shape and features over nearly the entire moon with a pixel scale close to 328 feet.

Major eruption in volcanic Moon Io

Jupiter's moon Io

This NASA montage of New Horizons images shows Jupiter and its volcanic moon Io, taken during the spacecraft’s Jupiter flyby in early 2007. The image shows a major eruption in progress on Io’s night side, at the northern volcano Tvashtar. Incandescent lava glows red beneath a volcanic plume, whose uppermost portions are illuminated by sunlight. The plume appears blue due to scattering of light by small particles within it.
