SPACE: The Sun’s a Little Crazy Right Now

by
solar flares - NASA

A series of rapid-fire solar flares is providing the first chance to test a new theory of why the sun releases its biggest outbursts when its activity is ramping down. Migrating bands of magnetism that meet at the sun’s equator may cause the biggest flares, even as the sun is going to sleep. A single complex sunspot called Active Region 2673 emitted seven bright flares — powerful bursts of radiation triggered by magnetic activity — from September 4 to September 10. Four were X-class solar flares, the most intense kind. The strongest, released at 8:02 a.m. EDT on September 6, … Read more

SPACE: Best. Job. Ever.

by
Planetary Protection Officer

From the NASA job website: Planetary Protection Officer This position is assigned to Office of Safety and Mission Assurance for Planetary Protection. Planetary protection is concerned with the avoidance of organic-constituent and biological contamination in human and robotic space exploration. NASA maintains policies for planetary protection applicable to all space flight missions that may intentionally or unintentionally carry Earth organisms and organic constituents to the planets or other solar system bodies, and any mission employing spacecraft, which are intended to return to Earth and its biosphere with samples from extraterrestrial targets of exploration. This policy is based on federal requirements … Read more

SPACE: Nasa to Test Earth Defense System

by

NASA scientists are excited about the upcoming close flyby of a small asteroid and plan to use its upcoming October close approach to Earth as an opportunity not only for science, but to test NASA’s network of observatories and scientists who work with planetary defense. The target of all this attention is asteroid 2012 TC4 — a small asteroid estimated to be between 30 and 100 feet (10 and 30 meters) in size. On Oct. 12, TC4 will safely fly past Earth. Even though scientists cannot yet predict exactly how close it will approach, they are certain it will come … Read more

SPACE: Pictures from that Jupiter Flyby

by
Jupiter Red Spot

Images of Jupiter’s Great Red Spot reveal a tangle of dark, veinous clouds weaving their way through a massive crimson oval. The JunoCam imager aboard NASA’s Juno mission snapped pics of the most iconic feature of the solar system’s largest planetary inhabitant during its Monday (July 10) flyby. The images of the Great Red Spot were downlinked from the spacecraft’s memory on Tuesday and placed on the mission’s JunoCam website Wednesday morning. “For hundreds of years scientists have been observing, wondering and theorizing about Jupiter’s Great Red Spot,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in … Read more

SPACE: NASA Craft Flies Over Jupiter’s Red Spot

by
Cassini Jupiter

Scientists are about to get an up-close and personal look at the planet Jupiter’s most famous landmark, the Great Red Spot. NASA’s Juno spacecraft will be directly over the spot shortly after 10 p.m. ET Monday, July 10, about 5,600 miles above the gas giant’s cloud tops. That’s closer than any spacecraft has been before. The spot is actually a giant storm that has been blowing on Jupiter for centuries. It’s huge, larger than Earth in diameter. Not only will Juno’s camera be able to capture detailed images of the spot, but the probe also carries scientific instruments that can … Read more

NASA Captures Views of Brightest Galaxies

by
Hubble Galaxies

Boosted by natural magnifying lenses in space, NASA’s Hubble Space Telescope has captured unique close-up views of the universe’s brightest infrared galaxies, which are as much as 10,000 times more luminous than our Milky Way. The galaxy images, magnified through a phenomenon called gravitational lensing, reveal a tangled web of misshapen objects punctuated by exotic patterns such as rings and arcs. The odd shapes are due largely to the foreground lensing galaxies’ powerful gravity distorting the images of the background galaxies. The unusual forms also may have been produced by spectacular collisions between distant, massive galaxies in a sort of … Read more

SPACE: Mars is Made of Swiss Cheese

by
Mars

Yeah, ok, so not really. But it sure seems that way in a new image from NASA, which also shows a mysterious pit: This observation from NASA’s Mars Reconnaissance Orbiter show it is late summer in the Southern hemisphere, so the Sun is low in the sky and subtle topography is accentuated in orbital images. We see many shallow pits in the bright residual cap of carbon dioxide ice (also called “Swiss cheese terrain”). There is also a deeper, circular formation that penetrates through the ice and dust. This might be an impact crater or it could be a collapse … Read more

SPACE: Beautiful New Video of Jupiter

by
Jupiter South Pole

NASA released a beautiful new video of Jupiter, showing the Solar System’s largest planet in a way we’ve never seen it before. The images were taken by the Cassini spacecraft, and include huge circular storms in the planet’s atmosphere. Enjoy!

SPACE: Three Planet Hunters Make Time List

by
Planet Hunters

Three extraordinary planet-hunters have been recognized by TIME Magazine as this year’s top 100 most influential people: Natalie Batalha from NASA’s Ames Research Center in California’s Silicon Valley; Michael Gillon from the University of Liège in Belgium; and Guillem Anglada-Escudé from the Queen Mary University in London. “It is truly exciting to see these planet-hunters among the other movers and the shakers of the world,” said Paul Hertz, Astrophysics division director at Headquarters in Washington. “These scientists have transformed the world’s understanding of our place in the universe, and NASA congratulates them for their well-deserved recognition.” Natalie Batalha is the … Read more

Where No Gay Has Gone Before: Fashionistas in Space!

by

When many of us hear the word ‘fabrics’, we immediately think of avant-garde, haute couture dresses, the latest fashions from Paris, or ‘who-is-wearing-who’ on the Red Carpet.  In space exploration, however, fabrics have more applications than for just snazzy clothes, like antennas, spacesuits and shields for spacecraft. Raul Polit Casillas, a systems engineer at NASA’s Jet Propulsion Laboratory in Pasadena, California, is the son of a fashion designer from Spain, so he grew up familiar with fabrics.  Now he is applying his knowledge and skills to develop woven metal fabrics for applications in space. The fabrics that Polit Casillas and … Read more
