Hubble celebrates New Year with new star birth photo

NASA‘s Hubble Space Telescope has captured an image of a galaxy 45 million light years away, described as “bursting with new star formation” as a vastly-powerful black hole churns through matter. The photo – of the NGC 1097 galaxy – centers on a black hole 100 million times the mass of our own sun and, as we tick over into a new year, shows the evolution of new solar systems.

NGC 1097 is what’s known as a Seyfert galaxy, characterized by intense brightness at their core. There, despite the voracious appetite of a supermassive black hole, a huge amount of radiation is thrown out as clouds of ionized hydrogen are released.

It’s that frothing of material swooping its way into the black hole that makes Seyfert galaxies such hot-beds for new star formation. “The ring is around 5000 light-years across,” NASA says, “although the spiral arms of the galaxy extend tens of thousands of light-years beyond it.”

Galaxy-gazing has become headline news in recent weeks, with predictions that the first “Earth twin” will be identified sometime in 2013. Obviously the forming stars around spiral galaxy NGC 1097 are a little too young to deliver that; it’s suggested that the High Accuracy Radial velocity Planet Searcher (HARPS) will be most likely to identify a suitable candidate, rather than Hubble.

The Real Story Behind Neil Armstrong’s History-Making Line

We all know the line, but what about the story behind it? Neil Armstrong was always keen on telling folks that he’d thought up the historical words after landing on the moon, but before the walk. That is to say, relatively off-the-cuff. A new documentary tells a slightly different story. More »

Curiosity plays peekaboo: New self-shot before 9-month mountain climb

NASA’s Curiosity rover has set mountain climbing as its New Year’s Resolution, with the intrepid space explorer headed up a Martian peak  for its 2013 challenge. The nine-month trek – punctuated with pitstops for drilling and sample analysis – will see Curiosity clamber up the 3 mile high Mount Sharp at the center of the Gale Crater it landed near, further hunting evidence that the red planet might once have supported microbial life. Before that, however, Curiosity couldn’t resist snapping another self-portrait – with the mountain clearly visible in the background.

curiosity_self-shot

Originally, the Mount Sharp expedition was expected to have begun before 2012 is through; however, mission chief scientist John Grotzinger told the AP, delays were introduced in the latter half of the year. At full speed, the rover is capable of around 90 meters per hour, though a more typical rate is a third of that.

Under automatic navigation, that pace drops again to more like 200m per day, given the challenges of roaming the foreign terrain. However, NASA is likely to manually drive Curiosity to make effective use of time, as well as to help refine the systems. A software update is already planned before the mountain trek starts in mid-February.

Ahead of the climb, Curiosity will spend a month or so hunting the so-called “perfect” rock to take samples from, a lengthy process of selection, core extraction, and testing in its bank of onboard labs. Grotzinger, a geologist, has said the Jet Propulsion Lab (JPL) in charge of the rover project has “promised everybody that we’re going to go slowly” despite the eagerness to tackle Mount Sharp.

Curiosity identified water, chlorine, sulfur, and other chemicals in recent tests, as well as other evidence that water had flowed on the Martian surface at one point in time. Next up on the checklist are the sort of chemicals that would be required for microbes to flourish, and which the JPL team believe are likely to be in the multiple strata of the mountain, assuming they’re present at all.

As for the self-portrait, the image is in fact made up of more than fifty smaller shots, taken by Curiosity’s Mars Hand Lens Imager on the end of the primary robotic arm. By panning the arm around the body of the rover, Curiosity could fire off enough images – over the course of a day – that the JPL team could stitch together into a panoramic shot, a process explained in the video below.

Earth microbes can survive on Mars, study finds

In a study published in the Proceedings of the National Academy of Sciences, scientists from the Russian Academy of Sciences and the University of Florida show that the anaerobic organism Carnobacterium can survive on the Red Planet. This comes after years of belief that any Earth microbes that make their way to Mars via devices sent there, such as the Curiosity rover, won’t survive the conditions. In light of this information, scientists have to be more careful than ever to avoid sending microbes to the Martian planet.

The scientists involved in the project harvested the bacteria from between 40 to 65-feet in the Siberian permafrost. This location was chosen because of its harsh conditions; according to the study, the microbes were harvested from permafrost that had an average temperature of 19 degrees Fahrenheit. Once harvested, they were grown into larger cultures in a lab for the experiment.

Once the larger culture was grown, the scientists exposed them to Mars-like conditions, such as very low-oxygen environment and extremely cold temperatures. The project took place over the course of a month, and out of 10,000 isolates subjected to the Martian conditions, all but six of them died. The six that remained, in an unexpected plot twist, thrived under the conditions.

The surviving Carnobacterium are, alas, not limited to the deep Siberian permafrost, and are instead found across the world, and on common items, such as ready to eat meal packaging. This information turns previously held beliefs upside down, and demonstrates the need for extra diligence in ensuring that humans do not contaminate Mars with Earth microbes.

Mars Express christens new space antenna with red planet pics

NASA’s Curiosity rover may be getting us close-up to Mars, but the European Space Agency’s Mars Express probe has a far more macro perspective as it beams back the first shots to be received at the new Malargüe space tracking station. Powered up earlier this month, the ultra-sensitive radio antenna funneled back shots from the Mars Express’ Visual Monitoring Camera showing the red planet from over 6,000 miles away.

Mars Express was launched back in 2003, and was intended to deliver the Beagle 2 rover to the surface of the planet. That part of the mission failed; however, the orbiter section has continued to take high-resolution shots of Mars and has seen its operation extended until 2014.

Malargüe DS3, July 2012

The ESA Malargüe station stands forty meters tall, with the antenna section along weighing in at 610 tonnes and able to track ongoing missions at both Mars and Venus. It will also be used for radio science experiments, such as trying to identify the different types of matter transmissions pass through.

It is located 1500m high in Argentinia, and features a 20 kW amplifier to send instructions all the way to Jupiter and beyond. In contrast, a typical cellphone has a 125 milliwatt amplifier. The dish was able to receive the Mars Express’ photos sent from 327 million kilometres away in just over 18 minutes.

Routine service of the antenna will begin early in 2013.

Earth twin will be discovered in 2013, according to scientists

Exoplanets have been popping up in the world of astronomy with relatively high frequency over the last half decade or so, with the latest one being the 51 Pegasi b that was revealed back in October. Thanks to advances in technology and other factors, it is likely the first “Earth twin” planet will be discovered next year, according to scientists.

public-domain-earth-for-blog

Thus far, exoplanets that have been discovered, while sharing characteristics with Earth, all possess factors that make them uninhabitable. 51 Pegasi b, for example, is close to its star, and as such, is extremely hot, rendering its landscape a scorched wasteland. Thus far, a legitimate Earth twin planet remains the subject of science fiction.

Multiple scientists and researchers believe that 2013 is the year when the first habitable planet similar in landscape and size to Earth will be found. The University of California, Berkeley’s Geoff Marcy stated: “The first planet with a measured size, orbit and incident stellar flux that is suitable for life is likely to be announced in 2013.”

The Earth twin will likely be discovered by High Accuracy Radial velocity Planet Searcher, more commonly called HARPS, the same technology that uncovered the exoplanet 51 Pegasi b. Says the University of Hertfordshire’s Mikko Tuomi, “Estimating carefully, there are 200 billion stars that host at least 50 billion planets, if not more. Assuming that 1:10,000 are similar to the Earth would give us 5,000,000 such planets.”

Russia’s new spaceship will fly you to the moon, let you swing among the stars

Russias new spaceship will fly to you the moon, let you swing among the stars

Russia’s protracted attempts at replacing the aging space warhorse that is Soyuz may finally bear fruit. RSC Energia has announced that it has finished the design of a prototype spacecraft under the country’s Prospective Piloted Transport System — the equivalent of the Orion program. The as-yet unnamed craft is expected to be ready for testing by 2017, and unlike the current model, will be fully reusable. It’s been designed not only as a taxi to take cosmonauts (and the odd multi-billionaire) to the International Space Station, but also ferry crews to the moon. That is, of course, assuming that Elon Musk doesn’t get there first and make the moon his summer home.

Landsat 5, a satellite that has been observing Earth since 1984, to be shutdown

The United States Geological Survey is poised to shut down the Landsat 5, an observational satellite that has been circling our fair planet since 1984. The announcement comes about 25 years after when the satellite was originally slated for deactivation. During its life span, Landsat 5 has taken over 2.5 million snapshots.

Landsat5

The satellite is being shut down due to a gyroscope that broke, which the USGS announced on December 21. The gyroscope cannot be repaired, and thus ends the Landsat 5′s long life. The satellite’s decommissioning won’t be instant, however, with the USGS stating that it will take place over most of 2013. The unit has made in excess of 150,000 trips around the Earth.

The Geological Survey’s Director Marcia McNutt offered this statement. “Any major event since 1984 that left a mark on this Earth larger than a football field was likely recorded by Landsat 5, whether it was a hurricane, a tsunami, a wildfire, deforestation, or an oil spill.” The Landsat legacy won’t die with the Landsat 5, however.

The USGS has another observational satellite in orbit, the Landsat 7, which was launched in 1999. Likewise, there are plans to launch another dubbed the Landsat 8 in February. The first Landsat satellite, the Landsat 1, was launched in July of 1972. Says Anne Castle of the Department of the Interior Assistant Secretary for Water and Science, “This is the end of an era for a remarkable satellite, and the fact that it flew for almost three decades is a testament to the NASA engineers and the USGS team who launched it and kept it flying well beyond its expected lifetime.”
