5:21 PM | Voyager has hit interstellar space…. maybe?
Poor Voyager, he just can’t catch a break. We’ve said it’s hit interstellar space more times than we want to admit and in 2012, the Voyager mission team announced that […]

7:26 PM | Kepler-421b: Astronomers Discover Exoplanet with Longest Known Year
A year on the newly discovered Uranus-sized exoplanet Kepler-421b lasts for 704.2 days, making it the longest orbital period exoplanet yet found. Its parent star, Kepler-421, is a G9/K0 dwarf star located in the constellation Lyra, about 1,000 light-years from Earth. Kepler-421b orbits the star at a distance of about 177 million km. As a [...]

1:00 PM | The cosmos laughs at our puny particle colliders
A while back, a few other science writers and I were chatting idly on Twitter about how common Higgs bosons might be in the cosmos. Not because they stick around very long — their lifetime is incredibly short — but because there are a lot of high-energy collisions near black holes, in supernova remnants, and […]

12:21 PM | Aliens are Sinners
To paraphrase Carl Sagan: in one unremarkable galaxy among hundreds of billions, there is an unremarkable star among hundreds of billions of stars in that one galaxy. Around that star revolves a world with life. Some people who live on that world believe they are the center of the universe. Sagan nicely puts into perspective [...]

5:21 AM | Some Thoughts about Apollo 11 and Beyond…
History Was Made, Will it Be Made Again? We watched the whole Moon walk sequence last night and it’s amazing what I remembered from the first time and what made a WHOLE lot more sense now. The thing that really surprised me was how much work the guys had to do in their 2+ hours […]

1:00 AM | NASA Is Seeking Help In Potentially Finding Life On Jupiter’s Moon Europa (Video)
NASA is confident that underneath Jupiter’s moon Europa there could be more water than in our oceans here on Earth. So naturally, Europa has attracted a lot of attention, encouraging the curious to ask, “Could there be life on Europa?”. Currently, NASA is aiming to send a new mission to Europa by 2025. The White House’s […]

12:49 AM | Messier Monday: The Most Perfect Elliptical, M89 (Synopsis)
“We sail within a vast sphere, ever drifting in uncertainty, driven from end to end.” -Blaise Pascal By now, you’ve probably learned that Messier objects — and galaxies in particular — come in a huge, rich variety of types, structures and compositions. But sometimes, the simplest structure of all is the rarest. Think about it: most…

Behold: The Beauty of Solar Magnetism NEW VIDEO! As massive magnetic fusion reactors go, the sun is pretty awesome. This week’s video features all the violence and beauty that erupt from that big bright thing at the center of our solar system. We’ve got sunspots, coronal loops, solar flares, coronal mass ejections! Even an aurora or two! And thanks to the fine people of NASA and their fancy satellites, this one is dripping with #spaceporn.

10:20 PM | For the First Time, We've Found an Exoplanet at the "Frost Line"
Astronomers have documented thousands of exoplanets to date, but they have yet to find one near the "frost line" — an important boundary in understanding how planets form. The discovery of Kepler-421b now changes that.Read more...

6:10 PM | 4 Sky Events This Week: Saturn Stands While Meteors Fly
Saturn, the true “Lord of the Rings,” dominates the evening sky this week, while the summer’s first meteor shower gets under way. Saturn at full stop. On Monday, July 21, the ringed world will appear at a standstill in the sky, relative to the background stars in the zodiacal constellation Libra, the Scales. Astronomers call this…

1:30 AM | Strange Shape to a Comet We are About to Visit
On Wednesday, August 6, the European spacecraft Rosetta is going  to have a close encounter of the best kind with a comet (a chunk of cosmic ice mixed with dirt.)  It's called Comet 67P (the P stands for periodic comet, meaning it comes around again and again every six and a half years.)  Its more informal name is Comet Churyumov–Gerasimenko, after the two astronomers who discovered it on a 1969 photograph. In mid-July when our photo was taken, the spacecraft was still […]

12:46 PM | The Silent Centennial of Space Exploration
Noisy revolutions often emerge from quiet beginnings. So it was with the revolution of the Space Age. Forty five years ago today, a Saturn V rocket roared off from Cape Kennedy and carried the first humans to the moon; Buzz Aldrin and many others are marking the anniversary with live and virtual reminiscences (NASA has […]The post The Silent Centennial of Space Exploration appeared first on Out There.

8:30 PM | As Rosetta Nears its Rendezvous With a Comet, Use this Way Cool Interactive Model to See How it Got There
The folks at Inove, creators of Solar System Scope, got in touch with me this morning to share their recent cool creation: an online, interactive, 3-D model of the Rosetta mission to Comet 67P/Churyumov-Gerasimenko. The European Space Agency’s Rosetta spacecraft has lately been going through a series of thruster burns to bring it to a […]The post As Rosetta Nears its Rendezvous With a Comet, Use this Way Cool Interactive Model to See How it Got There appeared first on ImaGeo.

8:26 PM | Scientists Discover Two Most Distant Stars Ever Detected in Milky Way Galaxy
A team of astronomers using the Red Channel spectrograph at the MMT Observatory on Mt. Hopkins in Arizona has discovered the most distant Milky Way stars known to date – ULAS J001535.72+015549.6 and ULAS J074417.48+253233.0. These cool red giants are extremely far away, at distances of 775,000 and 900,000 light years, respectively. The distant outskirts [...]

That is the question that a colleague of mine posed in response to the horrific events unfolding in Ukraine, Iraq, and Gaza (not to mention Pakistan, Afghanistan, Tunisia, Burma, and many other places that have been pushed out of the headlines in the hierarchy of bad news). In essence she was saying: “Time for some […]The post “How Can You Talk About Space Exploration at a Time Like This?” appeared first on Out There.

The sparks that appear on the baseball-sized rock (starting at :17) result from the laser of the ChemCam instrument on NASA’s Curiosity Mars rover hitting the rock. ChemCam’s laser zapping of this particular rock was the first time the team used Curiosity’s arm-mounted Mars Hand Lens Imager (MAHLI) camera to try and capture images of […]

“Two qualities are indispensable: first, an intellect that, even in the darkest hour, retains some glimmerings of the inner light which leads to truth; and second, the courage to follow this faint light wherever it may lead.” -Carl von Clausewitz You’ve been hanging around here long enough that you know all about dark matter’s successes,…

Splendid, isn’t it. It’s UGC 8335 — one name, so once it was apparently mistaken for one thing though obviously it’s two. They’re spiral galaxies in the process of running into and through each other. This is a photograph by the Hubble Space Telescope; the galaxies are really there; this is real.  You could think […]
