Hubble telescope photo of a spooky dead star will creep you out

A dead star takes on a ghostly green pallor in a new photo taken by the Hubble Space Telescope. The image, released conveniently in time for Halloween, reveals the remains of a star that exploded years ago as a supernova in the Crab Nebula, 6,500 light-years from Earth, leaving behind a “tell-tale heart,” according to NASA.

The tiny powerhouse is the bright star-like object near the center of the image.” Read more…More about Astronomy, Space Photos, Stars, Hubble Space Telescope, and Nasa

The Milky Way may be 50% bigger than previously thought

A ring-like filament of stars wrapping around the Milky Way may actually belong to the galaxy itself, rippling above and below the relatively flat galactic plane. If so, that would expand the size of the known galaxy by 50% and raise intriguing questions about what caused the waves of stars. Scientists used data collected by the Sloan Digital Sky Survey to reanalyze the brightness and distance of stars at the edge of the galaxy. They found that the fringe of the disk is puckered into ridges and grooves of stars, like corrugated cardboard.

Shape-Shifting Mirror Delivers Clearest Images of Space

A research team at the University of Arizona has captured the most precise images of the nights sky seen so far The Magellan Advanced Optics, or “MagAO,” is a specialized telescope filter that narrows details to .02 arcseconds — equivalent to seeing a baseball diamond on the moon. See also: Does the Future of the Space Industry Depend on Kickstarter? The improvement is thanks to a shape-shifting secondary mirror that corrects the imperfections of Earth’s atmosphere. It can do this almost in real time — 585 points on the mirror can change their positioning as fast as 1,000 times per second. This makes for the clearest visible-light images ever recorded — twice as sharp as images from the orbiting Hubble Space Telescope.

Northern Lights Dance in Spectacular Time-Lapse Videos

Jaw-dropping displays of the northern lights can be seen in a stunning series of time-lapse videos captured in Sweden this month by astrophotographer Chad Blakley. Blakley has been filming in Sweden’s Abisko National Park, which offers a view of glowing aurora borealis over snowy mountains. Swooshing and swirling green northern lights can be seen glimmering in a deep purple sky in the videos, which were shot over a 13-day stretch. “We have seen powerful auroras in the sky above Abisko for 13 nights in a row and it looks like there are more to come!” said Blakley, who runs the site LightsOverLapland.com. “Last night I witnessed one of the finest aurora displays I have seen in many… Continue reading… More About: nature, northern lights, space, sweden, Timelapse
