... Nasa reveals ‘really exciting’ first findings from underneath Mars . FOLLOW NBC NEWS MACH ON TWITTER, FACEBOOK, AND INSTAGRAM. Siebach said that while neither of the new discoveries "require life in the past or present, they present compelling evidence that Martian life could have existed in the past, that if it did we have a chance of finding evidence of it, and that there are ongoing reactions deep below the surface of Mars that could potentially be related to liquid water or life.". If you'd like to join in, send questions to the participants using the hashtag #askNASA no later than 1 p.m. EDT on June 7. As described in a pair of scientific papers published Thursday in the journal Science, Curiosity detected carbon-containing compounds in ancient sediments on Mars and shifting levels of the organic molecule methane in the planet's atmosphere.

New discoveries by NASA's Mars rover Curiosity add to a growing body of evidence supporting the idea that microscopic organisms once lived on the red planet — and have some scientists considering the possibility that microbial life lives there still. Interactive star chart showing the position of Mars and how to locate Mars in the sky.

Three new underground lakes have been detected near the south pole of Mars. It was launched from Cape Canaveral on Nov. 6, 2011, and landed on Mars on Aug. 12, 2012. NASA will provide details of key science findings from the agency’s ongoing exploration of Mars during a news briefing at 2 p.m. EST on Thursday, Nov. 5 in the James Webb Auditorium at NASA Headquarters in Washington. Editor's Note: NASA announced that the Curiosity rover uncovered tantalizing new evidence of organic molecules on the red planet. Scientists also confirmed the existence of a fourth lake - the presence of … Mars is one of the brighter planets and you will have no problem finding it in the heavens when it is in a dark sky and looking like bright red or yellow star. A self-portrait of the Mars Curiosity Rover from the Buckskin drill site, taken with the Mars Hans Lens Imager camera, reveals a rock stuck to the left middle wheel. News. The rover also found that sediments dating back more than 3 billion years contained a variety of organic molecules, a discovery described in the other paper, which was co-authored by Jennifer Eigenbrode, a biogeochemist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The event will be broadcast live on NASA Television and the agency's website. The space agency is offering scant details in advance of the event, which is scheduled to begin tomorrow (June 7) at 2 p.m. EDT, saying only that it has new "science results" to discuss. The latest breaking news, comment and features from The Independent. Curiosity, a tool-studded robotic vehicle weighing about 2,000 pounds, has been exploring Mars and conducting experiments for almost six years. full story about Curiosity's new findings, NASA to fly a helicopter on Mars, marking a first for interplanetary travel, Why robotic bees may be the next visitors to Mars, NASA's InSight mission will give Mars a long-overdue 'health checkup', This camera could boost the search for alien life. Image credit: Paul Sutherland Years ago, Curiosity found evidence that liquid water and the chemical ingredients for microbial life once existed on Mars. Just what has Curiosity discovered? This illustration shows the ways in which methane from the subsurface might find its way to the surface where its uptake and release could produce a large seasonal variation in the atmosphere as observed by Curiosity. Read the full story about Curiosity's new findings. "Both these discoveries are breakthroughs in astrobiology," Inge Loes ten Kate, an astrobiologist at the Utrecht University in the Netherlands, said in a written commentary published along with the papers. Online Planetarium Our Online Planetarium allows to compute the coordinates of planets, comets and asteroids and visualize them in the sky with respect to stars and constellations. In the paper about the new finding, Christopher Webster, a senior research scientist at NASA's Jet Propulsion Laboratory in Pasadena, California, and his co-authors conclude that "there remain unknown atmospheric or surface processes occurring in present-day Mars.". She said "the question of whether life might have originated or existed on Mars is a lot more opportune now that we know that organic molecules were present on its surface" in the distant past.

NASA has called a press conference to discuss new findings made by its Mars rover Curiosity, which has been exploring the Red Planet for six years.

NASA's 'Curiosity' has found tantalizing evidence of organic molecules on the red planet. Participants in the conference include Paul Mahaffy, director of the Solar System Exploration Division at NASA's Goddard Space Flight Center in Greenbelt, Maryland; Jen Eigenbrode, a research scientist at Goddard; Chris Webster, a senior research fellow at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California; and Ashwin Vasavada, Mars Science Laboratory project scientist at JPL. New Curiosity rover findings could mean breakthrough in search for signs of life on Mars, liquid water and the chemical ingredients for microbial life, Watch NASA test its supersonic parachute for future Mars mission, Debate heats up over the search for life on Mars, NASA's InSight mission will give Mars a long-overdue 'health checkup', Why robotic bees may be the next visitors to Mars. Methane can be produced by nonbiological processes, but on Earth it's created mostly by microorganisms. Curiosity landed on Mars on Aug. 6, 2012 with a mission to determine whether the Red Planet ever harbored life or had conditions suitable for life. So what's causing the varying methane levels on Mars? Curiosity rover finds evidence of Mars' ancient salty lakes "NASA concluded that the LR had found a substance mimicking life, but not life," said Levin in his article.

The event will be live-streamed here as well as on NASA's Facebook page and other social media platforms.

Mars rover's new discoveries hailed as 'breakthroughs in astrobiology' NASA's 'Curiosity' has found tantalizing evidence of organic molecules on the red planet. Mars shines brightly over the English Channel, shortly before opposition in 2018. The news conference participants will be: Curiosity landed on Mars on Aug. 6, 2012 with a mission to determine whether the Red Planet ever harbored life or had conditions suitable for life. The media and the public alike are invited to join the discussion via social media.

The car-sized rover hasn't found direct evidence of biological activity, but in 2013 it discovered that liquid water and the chemical ingredients for life once existed on Mars. But in one of the new discoveries, the car-size rover found that levels of methane in the Martian atmosphere vary widely from season to season, with levels peaking at the end of summer in the planet's northern hemisphere. The possibilities include reactions between water and rocks as well as "possible biological activity," Kirsten Siebach, a planetary geologist at Rice University in Houston, told NBC News MACH in an email.
