New membrane strips carbon dioxide from natural gas faster and better
A modified plastic material greatly improves the ability to separate global warming-linked carbon dioxide from natural gas as the gas is prepared for use, according to engineers at The University of Texas at Austin who have analyzed the new plastic's performance.   view more (2007-10-12)

Suzaku Snaps First Complete X-ray View of a Galaxy Cluster
The joint Japan-U.S. Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together.   view more (2009-05-29)

Jupiter`s Electric Aurora
The planet Jupiter has spectacular rings of auroras around each pole but until now scientists have not been able to explain how they form. All auroras are caused by energetic charged particles crashing into the top of the atmosphere and making it glow. In the Earth's auroras, these particles come from the Sun in a flow of charged particles known... view more... (2002-03-26)

Jupiter-like Planets Could Form Around Twin Suns
Life on a planet ruled by two suns might be a little complicated. Two sunrises, two sunsets. Twice the radiation field.    view more (2009-01-06)

Using microbes to fuel the US hydrogen economy
The focus on hydrogen as a future fuel source is compelling given dwindling supplies of oil and natural gas, as well as escalating costs and the fact that burning fossil fuels releases large amounts of carbon dioxide, a "greenhouse" gas, into the atmosphere.   view more (2006-09-13)

KTH research: Increased combustion reduces carbon dioxide emissions
New, previously overlooked technology could dramatically reduce emissions of carbon dioxide. Bio-energy facilities that capture carbon dioxide from combustion gases would even make it possible to reduce the amount of carbon dioxide in the atmosphere. The idea of capturing carbon dioxide and storing it in bedrock is not actually new. In recent... view more... (2001-11-23)

Expert challenges earthquake theory behind Indonesian mud volcano
A leading expert today repeated his assertion that an Indonesian mud volcano was almost certainly manmade despite a new study claiming the eruption might have been triggered by an earthquake.   view more (2007-08-01)

Biofuel carbon footprint not as big as feared, Michigan State University research says
Publications ranging from the journal Science to Time magazine have blasted biofuels for significantly contributing to greenhouse gas emissions, calling into question the environmental benefits of making fuel from plant material. But a new analysis by Michigan State University scientists says these dire predictions are based on a set of... view more... (2009-01-16)

Cosmic engines surprise XMM-Newton
XMM-Newton has been surprised by a rare type of galaxy, from which it has detected a higher number of X-rays than thought possible. The observation gives new insight into the powerful processes shaping galaxies during their formation and evolution.   view more (2008-04-08)

Burying the greenhouse gas
To prevent global warming, researchers and policymakers are exploring a variety of options to significantly cut the amount of carbon dioxide that reaches the atmosphere.   view more (2008-11-18)

Verification of national methane estimates now possible
New methods for verifying estimated greenhouse gas emissions, developed by scientists at Royal Holloway, University of London, will play a significant role in assessing reductions in methane emissions, important in national compliance with Kyoto protocol targets. David Lowry, Craig Holmes, Nigel Rata and Euan Nisbet of Royal Holloway’s... view more... (2001-04-25)

High-tech sieve sifts for hydrogen
Whether it's used in chemical laboratories or the fuel tanks of advanced automobiles, hydrogen is mostly produced from natural gas and other fossil fuels.   view more (2006-02-06)

Acoustic data may reveal hidden gas, oil supplies
Just as doctors use ultrasound to image internal organs and unborn babies, MIT Earth Resources Laboratory researchers listen to the echoing language of rocks to map what's going on tens of thousands of feet below the Earth's surface.   view more (2006-09-11)

Super sensitive gas detector goes down the nanotubes
When cells are under stress, they blow off steam by releasing minute amounts of nitrogen oxides and other toxic gases.   view more (2009-01-14)

NASA finds direct proof of dark matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter.   view more (2006-08-22)

Invention could solve "bottleneck" in developing pollution-free cars
Hydrogen-powered cars that do not pollute the environment are a step closer thanks to a new discovery which promises to solve the main problem holding back the technology.   view more (2006-12-05)

Chandra data reveal rapidly whirling black holes
A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects galaxy growth.   view more (2008-01-11)

Hubble sees magnetic monster in erupting galaxy
The Hubble Space Telescope has found the answer to a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example of the influence of these immense tentacles of extragalactic magnetic fields, say researchers.   view more (2008-08-21)

Smithsonian scientists highlight environmental impacts of biofuels
Biofuels reduce greenhouse-gas emissions in comparison to fossil fuels. In the Jan. 4 issue of the journal Science, Smithsonian researchers highlight a new study that factors in environmental costs of biofuel production. Corn, soy and sugarcane come up short.   view more (2008-01-04)

Stars stop forming when big galaxies collide
Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters.   view more (2008-10-08)
