5:00 PM | Stare Into The Raging Heart Of The Biggest Sunspot In 24 Years
The sun is spoiling us for superlatives. Last night, giant sunspot AR 2192 – the largest sunspot astronomers have observed in nearly 25 years – erupted in an X3.1-class solar flare, the most powerful of four flares to burst from the region since October 19th. Read more...

11:33 AM | Uncertain Dots 25: The Lightning Round
I got the time for the regular hangout wrong, and then we had some weird computer difficulties, so we only had ten minutes for Uncertain Dots this week. Which was enough time for me to say disparaging things about comic book movies, so, you know, if that interests you… Here’s the making of Interstellar story…

6:48 PM | How the Comet with the Funny Name Became a Globe-Trotting Internet Meme
I consider the Rosetta spacecraft one of the most exciting space voyagers in years. It is the first probe to orbit a comet, returning images of unprecedented richness. On November 12 it will place a lander on the comet’s surface, another exploratory breakthrough. Rosetta’s target, Comet 67P (its mouthy full name is Comet 67P/Churyumov-Gerasimenko) is […]The post How the Comet with the Funny Name Became a Globe-Trotting Internet Meme appeared first on Out There.

4:00 PM | And So It Begins…Nightfall Has Arrived.
Once again, I am making my pilgrimage to astronomical nirvana by attending Nightfall.  This year’s event is going to be a show stopper.  Not only is there the usual advanced courses available, this year there is a another complete track for not-so-advanced astronomers. Also, our sponsor, Woodland Hills Telescope will also have astronomical goods on … Continue reading →

11:21 AM | Hubble spots Comet Siding Spring flying past Mars
Comet Siding Spring makes near miss of Mars in this image form the Hubble Space Telescope. Click to enlarge! Image Credit: NASA, ESA, PSI, JHU/APL, STScI/AURA Last Sunday the comet C/2013 A1  Siding Spring flew past Mars at a distance of just 140 thousand kilometers, or one third of the distance between the Earth and the Moon. It's the closest we've ever seen a comet get to a rocky planet- so close, in fact, that initial observations suggested it might even hit.Data and observations […]

12:15 AM | Hawaiian natives protest Mauna Kea telescope
Politics or spiritualism? There remains hostility over the United States’ annexation of Hawaii and an undercurrent feeling of astronomy as an “industry”. Very weird to us but not weird to natives who feel intruded upon. Seeking Stars, Finding Creationism – NYTimes.com. This month a group of Native Hawaiians, playing drums and chanting, blocked the road… Source: Doubtful News

9:30 PM | Unlocking The Other Senses of Space
These days it’s no surprise to come across a gallery of amazing astronomy images. The Hubble Space Telescope, the other NASA great observatories and space probes, the European Space Agency and European Southern Observatory, and many, many dedicated amateurs (among other sources) provide a steady flow of visual riches. Mind-boggling beauty shows up every day; […]The post Unlocking The Other Senses of Space appeared first on Out There.

4:54 PM | Comet and Mars Take Interplanetary Selfie with Hubble
Comet Siding Spring Meets the Red Planet One of the benefits of having an amazingly keen-eyed space telescope like Hubble orbiting Earth is that you get great scenes like this one — Comet C2013 A1 Siding Spring passing by the planet Mars on October 19th. Hubble Space Telescope is actually so sensitive that scientists had to […]

3:16 PM | Astronomers Intrigued by Mysterious Zones of Organic Molecules on Titan
A multinational team of astronomers studying the chemical make-up of the atmosphere on Saturn’s moon Titan has revealed large zones of two organic molecules – hydrogen isocyanide (HNC) and cyanoacetylene (HC3N) – near the moon’s north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn [...]

8:56 PM | 500 Exocomets Found Orbiting Nearby Star Beta Pictoris
French astronomers using the HARPS instrument on the ESO 3.6-m telescope at the La Silla Observatory in Chile have discovered nearly 500 comets around the nearby star Beta Pictoris and have found that they belong to two distinct families: old comets that have made multiple passages near the star, and younger comets that probably came [...]

5:14 PM | Comet Madness
Beta Pictoris has Comets The southern hemisphere star Beta Pictoris has been one of the great “go to” places for exoplanet stories in the years since it was discovered to have a ring of debris around it by the IRAS satellite in 1983. To be specific, IRAS found excess infrared emission around the star, which […]

5:00 PM | Two Exocomet Families Found Around Baby Star System
Scientists have found two families of comets in the developing Beta Pictoris star system, located about 64 million light-years from Earth, including one group that appears to be remnants of a smashed-up protoplanet.

12:43 PM | The Death Star moon has a weird interior
Saturn’s small moon Mimas is best known for the giant crater Herschel, which makes it look like the Death Star. However, a new study based on Cassini data shows that its interior is weird too. While Mimas presents the same face to Saturn due to tidal-locking (just like the Moon does with Earth), it rocks […]

No Really, Look at It! You haven’t ever seen anything quite like this in your life. This is one of a continuing series of very cool images taken by the Rosetta’s NavCam imager from a distance of 9.8 kilometers from the center of the comet. What you see here is a region on the “neck” […]

8:39 PM | Iso-Propyl Cyanide Detected in Star-Forming Region Sagittarius B2
Astronomers using the Atacama Large Millimeter/submillimeter Array have detected an unusual carbon-based molecule called iso-propyl cyanide (i-C3H7CN) in Sagittarius B2, a giant molecular cloud of gas and dust located 27,000 light-years from Earth and just 390 light-years from the center of our Milky Way Galaxy. The search for molecules in space began in the 1960s, [...]

Come saprete i dati di BICEP che sembrava dovessero confermare l'inflazione cosmica e le onde gravitazionali primordiali hanno subito una verifica negativa. Come spiegano molto bene Amedeo e Sandro, l'interpretazione dei risultati è stata completamente ribaltata dalle analisi di Planck.Uno degli aspetti che, con quell'annuncio di metà aprile, non avevo trattato ma che mi sarebbe piaciuto era la questione dell'inflazione infinita.

1:16 PM | Flares Erupt from An Active Region on the Sun
The Sun has been acting up lately, producing one powerful X-class flare and several more moderate flares over the past 72 hours. You can see the X-class flare exploding off the lower left aspect of the Sun in the false-color image above, which was captured by NASA’s Solar Dynamics Observatory in the extreme ultraviolet wavelength […]The post Flares Erupt from An Active Region on the Sun appeared first on ImaGeo.
