The Hubble Space Telescope has been looking deep into the Cosmos for over two decades returning over a million observations of planets, exoplanets, nebulae, galaxies and clusters of galaxies. The mission has surpassed our wildest expectations, but some of the most intricately beautiful views of the Universe have been released only recently — sometimes in collaboration with other observatories.
“So, what do you do for a living?” “I just analyze data from radio telescopes… oh and I take pictures of black holes.” Pretty awesome job.
A giant black hole is thought to lurk at the center of the Milky Way, but it has never been directly seen. Now astronomers have predicted what the first pictures of this black hole will look like when taken with technology soon to be available.
In particular, researchers have found that pictures of a black hole ― or, more precisely, the boundaries around them ― will take a crescent form, rather than the blobby shape that is often predicted. Read more…
Skeletal ‘Nessie’ Discovered in Our Galaxy: The image above, looking into the plane of the galaxy, shows a long thin strand of dark, cold material stretching between two brighter regions in the lower half — this is a segment of what’s being called a “bone” of the Milky Way, a part of the vast skeletal structure that forms its framework.
And the bone is nicknamed… wait for it… “Nessie.” I love astronomers.
Did you get a shiny new telescope from Santa? If so, or if you just want to stand around the the backyard tonight looking at the stars, this guide is for you!
Astronomer and BBC presenter legend Sir Patrick Moore has died at the age of 89.
“It’s no exaggeration to say that Patrick, in his tireless and ebullient communication of the magic of astronomy, inspired every British astronomer, amateur and professional, for half a century.”
The first astronomy books I read as a child were all authored by Patrick. He’s an inspiration. A sad day. ~Ian
Is your telescope getting chilly? You’d better follow the advice of BBC astronomer/presenter Mark Thompson!
Don’t Freeze Your Telescope Off! “The advice of looking after your extremities is absolutely true and especially for astronomy. Standing around in a cold field doing little or no exercise means you must conserve as much heat as possible and the extremities is where your body loses it, fast.”
A new celestial wonder has stolen the title of most distant object ever seen in the universe, astronomers report. The new record holder is the galaxy MACS0647-JD, which is about 13.3 billion light-years away. The universe itself is only 13.7 billion years old, so this galaxy’s light has been traveling toward us for almost the whole history of space and time.
Resembling characters from a Tim Burton movie, these eerie figures are part of a molecular cloud of gas and dust located 1,400 light-years away in the constellation Cepheus. First identified in 1966, the human-like shapes with ‘arms’ raised give the nebula its spooky nickname: the “Ghost Nebula”.
