Spiral Galaxy? It’s big… damn big!

The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest-known spiral, based on archival data from NASA’s Galaxy Evolution Explorer (GALEX) mission. GALEX has since been loaned to the California Institute of […]

Free planets for everyone… NASA’s great new world rush.

NASA’s Kepler mission Monday announced the discovery of 461 new planet candidates. Four of the potential new planets are less than twice the size of Earth and orbit in their sun’s “habitable zone,” the region in the planetary system where liquid water might exist on the surface of a planet. One of the four newly […]

Voyager probe – finds alien life?

Well, maybe in the first Star Trek movie. In real life, though, NASA’s Voyager has just entered a new region far beyond our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space.  Scientists refer to this new region as a magnetic highway for charged particles because […]

Mercury… ice planet!

A NASA spacecraft studying Mercury has provided support for the long-held hypothesis the planet harbors abundant water ice and other frozen volatile materials within its permanently shadowed polar craters.  The new information comes from NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft. Its onboard instruments have been studying Mercury in detail since its […]

Kepler… King of the Planet Hunters!

NASA is marking two milestones in the search for planets like Earth; the successful completion of the Kepler Space Telescope’s 3 1/2- year prime mission and the beginning of an extended mission that could last as long as four years.  Scientists have used Kepler data to identify more than 2,300 planet candidates and confirm more […]

International Space Station: 1998-2011 (All Stages) by David Baker (book review).

You might have thought until now that I was only going to be reviewing Haynes fantasy output, but knowing what some of the books were coming up, I didn’t hesitate in adding the rather long titled ‘International Space Station: 1998-2011 (All Stages)’ to the list. As you can see from the cover, there’s a sub-title […]

Black hole flare’s one heck of a blast!

NASA’s newest set of X-ray eyes in the sky, the Nuclear Spectroscopic Telescope Array (NuSTAR), has caught its first look at the giant black hole parked at the center of our galaxy. The observations show the typically mild-mannered black hole during the middle of a flare-up. NuSTAR, launched June 13th 2012, is the only telescope […]

Astronomers discover amazing new galactic trend!

A study of hundreds of galaxies observed by the Keck telescopes in Hawaii and NASA’s Hubble Space Telescope has revealed an unexpected pattern of change that extends back 8 billion years, or more than half the age of the universe. “Astronomers thought disk galaxies in the nearby universe had settled into their present form by […]

The planets of Alpha Centauri!

John Grunsfeld at NASA had this to say to SFcrowsnest about the discovery of an exo-planet around Alpha Centauri, our nearest solar system. We congratulate the European Southern Observatory team for making this exciting new exoplanet discovery. For astronomers, the search for exoplanets helps us understand our place in the universe and determine whether Earth […]

X-ray nova!

NASA’s Swift satellite recently detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously unknown stellar-mass black hole. “Bright X-ray novae are so rare that they’re essentially once-a-mission events and this is the […]
