Astronomers have found a mind-bogglingly large structure — so big it takes light 10 billion years to traverse — in a distant part of the universe.
The discovery poses a conundrum to a fundamental tenet of modern cosmology, which posits that matter should appear to be distributed uniformly if viewed at a large enough scale. Read more
Comet ISON is currently diving through the inner solar system, soon to make a close approach with the sun on Nov. 28. Known as a “sungrazer comet,” ISON will dive deep into the sun’s corona, enduring the intense multi-million degree plasma and powerful solar energy. Since the “pristine” comet was discovered in September 2012, ground-based observatories, space probes and space telescopes alike have been trying to grab a glimpse of what could be the “Comet of the Century” should it survive its solar close approach. Although many of the space missions were not designed to take snapshots of comets, it hasn’t stopped many from trying and contributing valuable science as we continue to track ISON’s progress.

Gravitational waves are the elusive ripples in spacetime that are theorized to pervade the entire Universe, generated by violent events, chronicling the evolution of some of the most massive objects in the Cosmos. Now, by using a clever technique to measure the observed variations in pulsar spin rates, astronomers may be getting close to not only observing the presence of these waves, but also understanding why some of the biggest black holes are so fat.

It’s always a joy to see new views of the cosmos through a new telescope or instrument… and this is no exception — these are submillimeter-wavelength emissions from cool lanes of dust inside the Cat’s Paw Nebula, showing the locations of baby stars sparking to life. Read more about the new APEX instrument that is allowing astronomers to see deeper into the Cosmos than ever before.
The moon & Venus tonight, Middle Harbor Shoreline Park
This fantastic conjunction of Venus and the crescent moon was captured by DNews’ Executive Producer Pam from Oakland, CA! here’s what she had to say about the experience:
Pam: “I didn’t realize what I was capturing at first… I just thought the moon was pretty, because it was kind of low in the sky, right around sunset time. I thought ‘What’s that bright thing next to the moon?’ and remembered reading about the venus-moon conjunction happening this weekend and I was like, ‘RAD!’”
Rad indeed, Pam. Rad, indeed.
Astronomers have discovered something weird in the Milky Way’s galactic bulge — a population of planetary nebula are all mysteriously pointing in the same direction. Read more
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…
