Rosetta Comet 'pouring' more water into space

more »

There has been a significant increase in the amount of water "pouring" out of comet 67P/Churyumov-Gerasimenko, the comet on which the Rosetta mission's Philae lander touched down in November 2014. The 2.5-mile-wide (4-kilometer) comet was releasing the earthly equivalent of 40 ounces (1.2 liters) of water into space every second at the end of August 2014.

Watching the birth of a comet magnetosphere

more »

Astronomers have shown what happens when a magnetosphere forms round a comet. The RPC-ICA instrument onboard the Rosetta spacecraft has been watching the early stages of how a magnetosphere forms around Comet 67P Churyumov-Gerasimenko as it moves closer to the Sun along its orbit and begins to interact with the solar wind. As the comet gets warmer, volatile substances, mainly water, evaporate from the surface and form an atmosphere around the comet. The Sun's ultraviolet radiation and collisions with the solar wind ionizes some of the comet's atmosphere. The newly formed ions are affected by the solar wind electric and magnetic fields and can be accelerated to high speeds. When the comet gets close enough to the Sun, its atmosphere becomes so dense and ionized that it becomes electrically conductive. When this happens, the atmosphere starts to resist the solar wind and a comet's magnetosphere is born - a region surrounding the comet that is shielded from the solar wind.

Meteorite from Mars reveals further clues about atmosphere’s history

Science Focus

original post »

Mars has been the focus of a flurry of findings lately. The Curiosity rover has been exploring the Gale Crater, where it detected methane jets and also sampled clays from the dry lakebed there, discovering clues about the history of water and hydrogen on the planet. That points to Mars’ water, and hydrogen in its atmosphere, slowly being lost over a longer period than previously thought. Meanwhile, the MAVEN spacecraft, orbiting Mars, has observed the process that causes that loss.

Between the rovers and the MAVEN spacecraft, it’s no surprise that so many new findings have come to light. But amidst these discoveries, researchers have made yet another stride in understanding the planet’s history—and they’ve done so in a laboratory right here on Earth.

The meteorite, known as Allan Hills 84001, is named for the location in Antarctica where it was discovered in the 1980s. It originated on Mars and, crucially for the enterprise of studying the planet’s history, it’s about 3.9 billion years old. That puts its formation in the planet's water-rich Noachian era, so the carbonates it contains provide clues about this key period in the planet's history.

Telescope to seek dust where other Earths may lie

The NASA-funded Large Binocular Telescope Interferometer, or LBTI, has completed its first study of dust in the "habitable zone" around a star, opening a new door to finding planets like Earth. Dust is a natural byproduct of the planet-formation process, but too much of it can block our view of planets.

Gullies on protoplanet Vesta suggest past water-mobilized flows

more »

Protoplanet Vesta, visited by NASA's Dawn spacecraft from 2011 to 2013, was once thought to be completely dry, incapable of retaining water because of the low temperatures and pressures at its surface. However, a new study shows evidence that Vesta may have had short-lived flows of water-mobilized material on its surface, based on data from Dawn.

Stellar Nurseries RCW120 Rectangle Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space

Galaxies, Stars and Nebulae series

A fantastic set of stickers, with a monogram for you to change, featuring a colour composite image of RCW120.

It reveals how an expanding bubble of ionised gas about ten light-years across is causing the surrounding material to collapse into dense clumps where new stars are then formed.

The 870-micron submillimetre-wavelength data were taken with the LABOCA camera on the 12-m Atacama Pathfinder Experiment (APEX) telescope. Here, the submillimetre emission is shown as the blue clouds surrounding the reddish glow of the ionised gas (shown with data from the SuperCosmos H-alpha survey). The image also contains data from the Second Generation Digitized Sky Survey (I-band shown in blue, R-band shown in red).

Launch to Lovejoy

more »
Blasting skyward an Atlas V rocket carrying a U.S. Navy satellite pierces a cloud bank in this starry night scene captured on January 20. On its way to orbit from Space Launch Complex 41, Cape Canaveral Air Force Station, planet Earth, the rocket streaks past brightest star Sirius, as seen from a dark beach at Canaveral National Seashore. Above the alpha star of Canis Major, Orion the Hunter strikes a pose familiar to northern winter skygazers. Above Orion is the V-shaped Hyades star cluster, head of Taurus the Bull, and farther still above Taurus it's easy to spot the compact Pleiades star cluster. Of course near the top of the frame you'll find the greenish coma and long tail of Comet Lovejoy, astronomical darling of these January nights.

The Hubble Ultra Deep Field Space Image Case For The iPad Mini

Here's a great iPad case from Zazzle featuring a Hubble-related design. Maybe you'd like to see your name on it? Click to personalize and see what it's like!


tagged with: deep space, hubble, hubble deep field, hubble ultra deep field, deep field, astronomy, cosmology, constellation fornax, fornax, hudf

The Hubble Ultra-Deep Field (HUDF) is an image of a small region of space in the constellation Fornax, composited from Hubble Space Telescope data accumulated over a period from September 24, 2003, through to January 16, 2004. Looking back approximately 13 billion years (between 400 and 800 million years after the Big Bang) it will be used to search for galaxies that existed at that time. The HUDF image was taken in a section of the sky with a low density of bright stars in the near-field, allowing much better viewing of dimmer, more distant objects. The image contains an estimated 10,000 galaxies. In August and September 2009, the Hubble's Deep Field was expanded using the infrared channel of the recently attached Wide Field Camera 3 (WFC3). When combined with existing HUDF data, astronomers were able to identify a new list of potentially very distant galaxies.

This nebula is brimming with new-born stars, many as young as only a million years of age. It's called the Tadpole nebula because the masses of hot, young stars are blasting out ultraviolet radiation that has etched the gas into two tadpole-shaped pillars, called Sim 129 and130, the yellow forms that seem to be swimming away from the three red stars close to the centre of the picture.
