The Curiosity Rover’s Ultimate Self-Portrait

OK, we thought the low-resolution self-portrait from yesterday was great… but here’s the real goods: a monster, high-resolution awesome mosaic of 55 images taken by the Mars Hand Lens Imager (MAHLI), showing the rover at its spot in Gale Crater — called Rocknest — with the base of Gale Crater’s 5-kilometer- (3-mile-) high...

Timelapse of Hurricane Sandy, Satellite Views October 23-31, 2012

  • PDF

Here’s a complete animation of Hurricane Sandy from October 23-31, as seen by GOES-13, a geosynchronous satellite that is in orbit nearly 36,000 km (23,000 miles) above Earth. This huge storm was costly in terms of death and destruction. The death toll currently stands at 160 (88 in the U.S., 54 in Haiti, 11 in Cuba), with damage estimates ranging from $10 – $55 billion.

Below is a timelapse animation which shows the full hemisphere...

Could Plasma Jet Thrusters Kickstart Interplanetary Travel?

A great offshoot from commercial space companies getting a foothold in real missions to orbit is that the old entrepreneurial space spirit seems to have been revived. People are attempting to develop and build what could be breakout space technologies, sometimes in their garages or basements. A new Kickstarter project is especially exciting, as it is looking to build a prototype electric pulsed plasma jet thruster, and the engineers behind...

Fermi Measures Light from All the Stars That Have Ever Existed

All the light that has been produced by every star that has ever existed is still out there, but “seeing” it and measuring it precisely is extremely difficult. Now, astronomers using data from NASA’s Fermi Gamma-ray Space Telescope were able to look at distant blazars to help measure the bac...

Curiosity Rover Takes an Incredible Self-Portrait

Wow, what a view of the Curiosity rover! This is a self-portrait mosaic made from brand new images taken by the MAHLI (Mars Hand Lens Imager), the high-resolution camera located on the turret at the end of MSL’s robotic arm. The arm was moved for each of the 55 images in this mosaic, so the arm doesn’t show up in the mosaic. This montage was put together by Stuart Atkinson, and he notes that these images are just the low-res...

Vesta Looks Forever Young

This image from NASA’s Dawn spacecraft shows a close up of part of the rim around the crater Canuleia on the giant asteroid Vesta. Canuleia, about 6 miles (10 kilometers) in diameter, is the large crater at the bottom-left of this image. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/PSI/Brown

From a ULCA press release:

Like a Hollywood starlet constantly retouching her makeup, the giant asteroid Vesta is constantly stirring its outermost layer...

Minute Physics: Why E=mc² is Incomplete

  • PDF

Here’s another great video from the folks at Minute Physics. One of the most famous equations from one of the world’s most famous scientists is a bit more complicated than many people realize. E=mc² only describes objects with mass that aren’t moving. But what about massless particles – like light – that are moving? Check out the video for a quick explanation!

Iceland is a land of stark beauty and extremes in both weather and landscape. But its also a place to see some of the most spectacular views of northern lights. Jean-Luc Dauvergne a journalist from Ciel Et Espace, a French astronomy magazine, recently traveled to Iceland and said in an email to Universe Today, “I think that this...

From an ESA press release:

Two massive stars racing in orbit around each other have had their colliding stellar winds X-rayed for the first time, thanks to the combined efforts of ESA’s XMM-Newton and NASA’s Swift space telescopes. Stellar winds, pushed away from a massive star’s surface by...
