Is there Martian life on Earth?

Is there Martian life on Earth?

The geochemists get a poor press, so they must have decided to soup up their theories and grab some oxygen for their reputation. The claim is that being impossible on earth, ribose sugars can only have been synthesised on Mars, 4 billion years ago. And then...

Scientists have used gravitational lensing to increase the power of the Hubble telescope and examine a quasar ring around a black hole. Using the Hubble Space Telescope, scientists examined the bright ring of matter, called a quasar accretion disc, possibly 300 billion kilometres wide, which is slowly disappearing into the black hole.

Ice Warms in Antarctica

The wild west of Antarctica has many thinning glaciers such as the huge Getz Ice Shelf, the Pine Island Glacier, and the Thwaites Glacier. NASA's Ice Bridge Project is now in full production there, showing how this strategic locked-up water is liable to be released quicker than we thought, causing higher sea levels worldwide.

A discovery of three new planets and a mystery object orbiting with them has been discovered. A international research team have discovered a group of three new planets that are all in orbit around their own dying giant stars. The Hobby-Eberly Telescope was used by the team that is led by an astronomer from Penn state University; they have named the three planets HD 240237, BD +48 738 and HD 96127.

Astronomers from the European Southern Observatory in Chile have announced the discovery of two new rare globular clusters of stars in the heart of our Milky Way galaxy. The discoveries represent the fruits of an ambitious project to survey the center of the galaxy in infrared light.

Mars Carbs.

Mars Carbs.



The oldest rocks known include the Martian meteorite ALH84001, from the Allen Hills in Antarctica. Geologists believe it started life, 4 billion years ago, tens of metres below the Martian surface and was 'snookered' off the planet by another meteorite when it struck that area, a mere 16 million years ago.

ESO travel through time with VLT

ESO travel through time with VLT

Very Large Telescope (VLT) researchers time-travel back to 1 billion years after the Big Bang. Up to that time neutral hydrogen fogged the view of early events in the young galaxies as they 'reionised'. This age of reionisation now has a timeline, after a three year search with the VLT for distant galaxies at this stage of development.

NASA's continuing monitoring of the ice in the seas around the Arctic has confirmed that the sea ice extent has shrunk close to its 2007 record low confirming a 30 year declining trend. Each year the ice expands through the winter before melting away as the sun warms the northern hemisphere, reaching its minimum level in September.

Japanese tsunami broke chunks off Antarctica's ice sheet

Photographic evidence has emerged that suggest the Japanese earthquake and subsequent Tohoku Tsunami caused 50 square miles of ice to break off Antarctica. Images from the European Space Agency show that icebergs, some larger than Manhattan island, broke away from Antarctica just a few days after the quake.

Hot Jupiters - Flipped or Otherwise

Hot Jupiters - Flipped or Otherwise

A ''hot Jupiter'' is a planet larger than the Jupiter of our own solar system which occupies an orbit close into its own star - hence ''hot Jupiter''. The conundrum was why should these giants be travelling in the wrong direction?

Much of ancient Martian atmosphere frozen at poles

Much of ancient Martian atmosphere frozen at poles

Mars may well have had a much denser CO2-rich atmosphere hundreds of thousands of years ago - one with wilder dust storms and that was more likely to support running water. That's the claim coming from a new analysis of satellite radar data over the Martian southern ice cap - published in Science today - which hints at a thick wedge of frozen CO2 there that contains 30 times the 'dry ice' of previous estimates.

Record-breaking 2010 Amazon drought seen from space

Record-breaking 2010 Amazon drought seen from space



Last summer's drought in the Amazon left vast swathes of forest visibly stressed, according to a study of images from 2 NASA satellites. This worryingly matches the predictions of drier, harsher times for one of the world's most biodiverse areas - and sets the scene for possible massive outpouring of CO2.

More ice leaving polar ice sheets than ever before

More ice leaving polar ice sheets than ever before

A new NASA-funded satellite study of the polar ice sheets shows an alarming accelerating trend of ice loss from both Greenland and Antarctica. Combined with losses from mountain glaciers and ice caps this could result in a global sea level rise of 32cm as early as 2050. Filed in environmental issues: Sea Levels/Climate

Newly discovered mature galaxy cluster, revised big bang theory?

Newly discovered mature galaxy cluster, revised big bang theory?

A recently discovered mature cluster of galaxies seems to be a rare phenomenon - or could the universe have developed differently from what is currently thought? Scientists working from the European Southern Observatory (ESO) in Chile have recently discovered the furthest mature cluster of galaxies away from us which we can still see. Filed under: Science - Technology.

New insights into the formation of the Earth, the Moon and Mars

A team from the NASA Lunar Research Institute concludes that the Earth, Moon and Mars were formed as the result of massive solar impacts. It is known that siderophile, or metal-loving elements such as gold and platinum are common to the mantles of Earth, the Moon and Mars and new research has shown that massive impactors delivered this abundance during the final phase of planet formation
