This is How Saturn’s Rings Would Look to a Butterfly

You don’t typically see Saturn’s rings looking like this, but then you can’t see in ultraviolet like Cassini (or many insects) can! The image above was acquired by the UVIS (UltraViolet Imaging Spectrograph) instrument aboard the Cassini-Huygens spacecraft on June 30, 2004, just as it was entering orbit around Saturn. The area shown here is…

The Glory of Venus

Oh, glorious Venus! How fragrant are your sulphuric skies! How your rainbow clouds do shimmer! Actually the sulfuric acid-laden clouds of our neighboring planet would be anything but pleasant for humans, but ESA’s Venus Express orbiter did spot some iridescent hues as it flew over. The picture above, made from images acquired on July 24,…

A Ceres of Surprises: the Largest Asteroid is a Water World

By now you must know about the jets of ice particles blasting out of Saturn’s moon Enceladus, and maybe have even heard about the recent discovery of water vapor issuing forth from Jupiter’s frozen moon Europa. But now we know of another spray-happy world out there: Ceres, which at 591 miles across is our solar…

Wake Up, Rosetta!

It’s being called “the most important alarm clock in the solar system” —  tomorrow, Monday January 20, at 10:00 GMT (which is 5:00 a.m. for U.S. East Coasters like me) the wake-up call will ring for ESA’s Rosetta spacecraft, bringing it out of hibernation after over two and a half years in preparation of its…

The Brightest Lights: 12 Awesome Space Stories of 2013

What a year for space exploration! With 2013 coming to a close I thought I would look back on some of the biggest news in space that I’ve featured here on Lights in the Dark. Rather than a “top ten” list, as is common with these year-end reviews, I’m going to do more of a…

Jupiter’s Moon Europa Has Jets Like Enceladus!

“Attempt no landings there?” Ok, FINE. We’ll just fly a spacecraft through Europa’s newly-discovered plumes and get a taste of its underground ocean that way! Because it has them, and so we could. This was the big news from NASA, ESA, and Hubble researchers today: Jupiter’s ice-covered moon Europa (yes, the one from 2010) has…

Happy Birthday, ISS!

It’s been 15 years since the first piece of what we now know as the International Space Station left the surface of our planet. It was Russia’s Zarya module, launched aboard a Proton rocket on Nov. 20, 1998, and the U.S. followed suit two weeks later with the Unity module sent aboard the shuttle Endeavour….

Venus Has a Surprisingly Chilly Layer

Although similar in size to Earth, the planet-next-door Venus is typically perceived as a hellish inferno of caustic clouds, crushing pressures and kiln-like temperatures. And while those are indeed all very much the case, Venus has recently been found to have a cooler side too… although it’s 125 km (77 miles) up in its atmosphere.

Expedition 31 Sails Back to Earth

A Soyuz TMA-03M capsule descended to the steppes of Kazakhstan this morning at 4:14 a.m., returning Expedition 31 crew members Oleg Kononenko, Don Pettit and André Kuipers to Earth after 193 days working aboard the Space Station. The dramatic photo above was captured by NASA photographer Bill Ingalls, showing the Soyuz vehicle as it parachuted down…

Comet Lovejoy’s Dazzling Death Dive

The end is definitely near… for comet Lovejoy, at least. The bright sungrazing comet was discovered on December 2, 2011, by Australian amateur astronomer Terry Lovejoy using a ground-based telescope. It was quickly seen that the comet was on a doomsday dive toward the Sun and will not likely survive its close pass of our…

Mars Express Gets the Delta Blues

ESA’s Mars Express orbiter has imaged yet more evidence of a watery past on Mars with what appears to be the remains of a river delta, seen here, located just within the 40-mile (65-km) -wide Eberswalde Crater. Formed over 3.7 billion years ago, Eberswalde Crater was in the top 4 list of possible landing sites…

Slicing Into Mars’ Past

Deep gashes – called grabens – slice across the surface in the Nili Fossae region of Mars, seen above in an image from the Mars Express orbiter taken in February 2008. A German word meaning “ditch”, a graben is a downthrust strip of land bordered by scarps on either side. They are typically caused by…
