NASA Airship Could Watch The Stars Without The Need Of a Rocket

Dreams of space are often tied to jet engines or solar sails or taking a ride on a rocketship. But it's often quite efficient to do research from Earth, especially from the high reaches of the atmosphere where there are few molecules to get in the way of observations. NASA wants to do more of […]

Live Discussion: How Good is the Science of Interstellar?

... “Interstellar” is based on science and theory; from wormholes, to the push-pull of gravity on a planet, to the way a black hole might re-adjust your concept of time. But just how much of the movie is really true to what we know about the Universe? There has also been some […]

An Ocean Beyond Earth: Europa Awaits

... totally unknown to science. But what about the ocean on other worlds? I'm not talking¬about sci-fi planets or suspected alien Earths around other stars, either, but right here in our own solar system, where an ocean even deeper than ours […]

Dear Jupiter: Use More Sunscreen

It's the signature accessory of the largest planet in our solar system: Jupiter's Great Red Spot, an enormous anticyclone¬over twice the width of our entire planet. Visible in even modest backyard telescopes, the GRS has been churning away for¬at least several hundred years. But, based on recent analysis of data gathered by the Cassini spacecraft […]

A Thousand Days Til Totality: Anticipating the 2017 Solar Eclipse

Where will YOU be on August 21st, 2017? Astronomy is all about humility and thinking big in terms of space and time. It's routine for astronomers to talk of comets on thousand year orbits, or stars with life spans measured in billions of years(...)Read the rest of A Thousand Days ‘Til Totality: Anticipating the 2017 […]

BICEP2 All Over Again? Researchers Place Higgs Boson Discovery in Doubt

At the Large Hadron Collider (LHC) in Europe, faster is better. Faster means more powerful particle collisions and looking deeper into the makeup of matter. However, other researchers are proclaiming not so fast. LHC may not have discovered the Higgs Boson, the boson that imparts mass to everything, the god particle as some have called […]

Fibers and Voorwerpjes

While preparing for more observations of the Galaxy Zoo giant AGN clouds (Voorwerpjes), this is a good time to introduce more complete ways of obtaining astronomical spectra. Traditionally, we've put a long slit in front of spectrographs, so we can measure everything along that line without worries about overlapping spectra of different objects or pieces […]

Cosmic Castaways' Orphan Stars Shine in New Numbers

New research is occurring on up to half of the stars in the known universe, discovered to be drifting outside the safe havens of their home galaxies in unexpected numbers by a new study. CIBER, or the Cosmic Infrared Background Experiment, is a set of telescopes launched into space to briefly study the cosmic glow emitted by what scientists had previously thought to be the light of the Universe's first, primordial galaxies. During Astrophysicist Michael Zemcov and his team's obse

Rosetta mission team makes final plans to save Philae lander - as it happened

Time is running out for Philae as its original battery charge is exhausted and it receives insufficient sunlight on its solar arrays to carry on working. However, many of its scientific objectives have already been achieved 5. 55pm GMT Thats it for today. The Philae mission looks almost certain to be coming to an end. Tomorrow we will know one way or the other whether it has survived the night. It has been an extraordinary rollercoaster. Amid all the anxiety about the landers limited lifetime, beh

The cold gas thruster appears not to be working on Philae. This thruster is on top of the lander and is designed to push the spacecraft onto the comet as the harpoons and drills anchor Philae to the surface. Without the thruster, the risk of Phila

Rosetta comet landing on course despite wake-up glitch

Rosettas Philae lander did not wake up properly at the first attempt but everything is back on course nowOn Wednesday the European Space Agency will attempt a risky landing on a comet, and it seems the Philae lander wanted to catch a few extra winks of sleep before its big day. Overnight, the commands were sent to wake up Philae but the robotic lander began using a backup computer rather than the main computer. The result was that not all the telemetry data was being sent to Earth. Continue readi

Vesta's Giant Impact

Vesta is, in so many ways, the weirdest world that you are mapping here on CosmoQuest. It's small enough to be non-spherical and is covered in the scars of its many impacts. The largest impact basins on its southern pole are records of some of the most defining moments in Vesta's history. They are even responsible for the ridges around it s equator that first surprised scientists when the first high resolution images came back from Dawn. Recently, a group

Seven Days Out: ESA’s Historic Landing on a Comet is Just a Week Away

In less than a week, on November 12, 2014, the Philae lander will separate from ESA's Rosetta spacecraft and descend several kilometers down to the dark, dusty and frozen surface of Comet 67P/Churyumov-Gerasimenko. Its three spindly legs and rocket-powered harpoon are all that will keep the 100-kilogram spacecraft from crashing or bouncing hopelessly back out […]

How much would it cost to establish a space base close to Earth, say on the Moon or an asteroid? To find out, Universe Today spoke with Philip Metzger, a senior research physicist at NASA's Kennedy Space Center, who has explored this subject extensively on his website and in published papers. Yesterday, Metzger outlined the […]
