Kepler’s Supernova remnant provides possible evidence of explosion

Kepler’s Supernova, which is named after German astronomer Johannes Kepler, was one of the more popular supernovas in the visible universe, and it’s one of the more recent supernovas to have been visible to the naked eye at only 20,000 light years away from the Earth. Today, NASA posted up some recent findings of the supernova’s explosion based on remnants.

Observed with NASA’s Chandra X-ray Observatory, the remnant of Kepler’s Supernova shows red, green, and blue colors, which represent low, intermediate, and high energy X-rays. It has already been said that the type of explosion was a “Type Ia” supernova, or the thermonuclear explosion of a white dwarf star, but there’s an ongoing controversy about these types of explosions.

However, a recent study suggests that the explosion of Kepler’s Supernova was triggered by an interaction between a white dwarf and a red giant star. The evidence from Chandra shows a disk-shaped structure near the center of the supernova’s remnant, and researchers are saying that the explosion was caused by the collision between supernova debris and disk-shaped material that the giant star spit out.

Kepler’s Supernova was first discovered in 1604 by Kepler, and he ended up tracking the supernova for a full year. It was only the second supernova to be observed in a generation, and no further supernovas have since been observed like that within the Milky Way. The remnant left behind is said to be one of a kind, which is why many astronomers have been focusing on it for years.

NASA Jet Propulsion Laboratory’s Tom Rivellini backstage at Expand (video)

NASA Jet Propulsion Laboratory's Tom Rivellini backstage at Expand (video)

If you truly were terrified during the Seven Minutes of Terror that saw the Curiosity Rover successfully land on Mars, you can blame NASA Jet Propulsion Laboratory’s Tom Rivellini. As JPL’s Principal Engineer for Entry Descent and Landing Systems, Rivellini co-invented the sky crane landing system that helped the rover plant its wheels on the red planet. He met with us backstage to discuss the challenges that have been encountered with these feats of engineering, and what he’s currently working on: a new parachute and heat shield system for landing spacecraft carrying humans or larger rovers on Mars. Hit the jump for the full interview on video.

Space Exploration After the Shuttle liveblog

Space Exploration After the Shuttle liveblog

America’s space shuttle program may have come to an end when Atlantis was laid to rest at the Kennedy Space Center, but that’s done nothing to dampen our interest in the universe through which we float. NASA’s Curiosity captivates us with pictures and data from the Martian surface, and private ventures are popping up to replace shuttered, publicly funded programs. Join the SS Engadget for our panel on the future of space exploration — introduced by Patrick O’Neill of the ISS, steered by our captain Brian Heater, and manned by Tom Rivellini of NASA’s Jet Propulsion Laboratory, Alexandra Hall of Google’s Lunar X PRIZE, and Michael Laine of the LiftPort Group.

What a Giant Martian Mountain Would Look Like on Earth

The red planet is an alien world, and though it may have once held life, it’s certainly no Earth. But thanks to a recent, mammoth panorama shot by Curiosity, we can get a glimpse of what it would be like if one of Mars’ mountains was transplanted here to ol’ Terra. More »

James Webb Space Telescope ready for its wings, on track for 2018 launch

James Webb Space Telescope ready for its wings, on track for 2018 launch

What’s a spacecraft need wings for? Packaging, of course. The James Webb Space telescope relies on a 21 foot diameter backplane mirror to steady it, but the assembly needs to fit inside of a 16.5 foot fairing to ride the rocket to the stars. A tight fit, to say the least. Fortunately, NASA technicians have just finished the mirror backplate support structure, a folding wing assembly designed with to safely collapse the beryllium mirror during flight, and expand it again in orbit. “This is another milestone that helps move Webb closer to its launch date in 2018,” remarked Geoff Yoder, the program’s director. Now that the wing assembly is finished, the team can focus on the support fixture for the instrument model, which will complete major construction and allow technicians to connect the finished pieces. We’ll miss old Hubble, sure, but we’re happy to see its successor pulling things together all the same.

NASA readies first laser communications system for LADEE lunar satellite

NASA integrates its first laser communications system into LADEE lunar satellite

NASA has just finish testing and integration of its first high-data-rate laser communications system for the Lunar Atmosphere and Dust Environment Explorer (LADEE). The Lunar Laser Communication Demonstration presents a significant upgrade in existing data communications used in space — with an estimated increase of six times the throughput of the current best radio system. Unlike previous one-way demonstrations, the LCDD uses an infrared beam — in the same way that many land-based fiber networks do — that can be received on Earth by one of three telescopes located in Mexico, California or Spain. It’s not just about upping the data rate, though, as other challenges include keeping that signal good through conditions your ISP (thankfully) won’t normally have to consider, such as pin-point accuracy over 238,900 miles while moving through space. Going forward, the LLCD will play a vital part in NASA’s 2017 Laser Communications Relay Demonstration, a key test of laser-based relay comms in future missions. Back here on Earth, however, we never thought we’d get bandwidth-envy this far out in the sticks.

Russia and Europe team up for joint missions to Mars

ESA team builds self-piloting rover in six months, tests it in Chilean desert

We’re not sure how George Smiley would feel at the news, but we’re certainly pleased to see that Europe and Russia are teaming up to revive the moribund ExoMars missions. The ESA has signed a deal with Roscosmos, its Soviet counterpart, that’ll see the pair launch an orbiter to the Red Planet in 2016, followed by a rover mission two years later. Unsurprisingly, Russia will be chipping in the rockets, leaving Europe with the job of building the hardware that’ll go on it. Now all the pair need to do is argue about how best to usurp Curiosity as the mayor of the Gale Crater.

Mozilla launches Open Badges 1.0, delivers virtual kudos for real skills

Mozilla launches Open Badges 10, delivers virtual recognition for real skills

We’ve long missed the stickers and badges we could wear to show achievements in our childhood, whether it was an A+ in History or our campfire-making chops. Mozilla must miss those too, as it’s launching Open Badges 1.0, a spec for proving skills on the web. The approach provides verifiable credentials that are stowed away in a virtual Mozilla backpack and shareable through a number of online avenues, starting with WordPress blogs and Twitter updates. You won’t necessarily need to be a web scripting wizard to earn badges, either — they’re available or coming from 600-plus companies and educational institutions that include Disney-Pixar, NASA and the Smithsonian. We’re a long way from only having to flash our Open Badges to land a job, but those symbols may be enough to let teachers and coworkers know we’re up to snuff for key tasks.

Curiosity Rover Discovers Conditions On Mars Suited For Ancient Life

Curiosity Rover Discovers Conditions On Mars Suited For Ancient Life

It was late last summer when the Curiosity Rover made landed on Mars, and several months later, has stumbled onto an important discovery during its time on the red planet.

According to a NASA press release sent out today, the Curiosity Rover has come across conditions that could have supported living microbes. Lead Mars Exploration Program scientist Michael Meyer laid out today’s discovery.

“A fundamental question for this mission is whether Mars could have supported a habitable environment. From what we know now, the answer is yes.” (more…)
