Could Life on Earth Have Originated from Somewhere Else?

Could Life on Earth Have Originated from Somewhere Else

New research presented at the European Planetary Science Congress at UCL examines whether life forms would be able to survive an impact with the surface of the Earth, opening the door to the possibility that life did not originate on Earth but came from elsewhere in the universe. It sounds like science fiction, but the […]

Spitzer Reveals That Asteroid Don Quixote is a Comet

Astronomers Reveal Asteroid Don Quixote is a Comet

Data from NASA’s Spitzer Space Telescope helped astronomers discover that the large asteroid called Don Quixote is in fact a comet. For 30 years, a large near-Earth asteroid wandered its lone, intrepid path, passing before the scrutinizing eyes of scientists armed with telescopes while keeping something to itself. The object, known as Don Quixote, whose […]

New Research Explores the Possibility of Detecting Biomarkers on Distant Planets

New Research Aims to Detect Biomarkers on Distant Planets

New research presented to the European Planetary Science Congress at UCL aims to explore how atmospheric biomarkers from faraway planets might be detected in the future. On Earth, life leaves tell-tale signals in the atmosphere. Photosynthesis is ultimately responsible for the high oxygen levels and the thick ozone layer. Microbes emit methane and nitrous oxide […]

Study Reveals Copper Alloys Destroy Highly Infectious Norovirus

Copper Destroys Highly Infectious Norovirus

A newly published study reveals that copper alloys rapidly destroy the highly infectious norovirus. Scientists from the University of Southampton have discovered that copper and copper alloys rapidly destroy norovirus. Worldwide, norovirus is responsible for more than 267 million cases of acute gastroenteritis every year. In the UK, norovirus costs the National Health Service at […]

Quantum Tunneling Allows “Impossible” Chemical Reactions to Occur in Space

Quantum Tunneling Allows “Impossible” Chemical Reactions to Occur

A team of scientists from the University of Leeds has discovered that chemical reactions once thought to be ‘impossible’ in the coldness of space can actually occur thanks to a phenomenon called ‘quantum tunneling.’ New research has revealed that chemical reactions previously thought to be ‘impossible’ in space actually occur ‘with vigor,’ a discovery that […]

Astronomers Deduce the Characteristics of Nanodust

Astronomers Use STEREO Spacecraft to Deduce the Characteristics of Nanodust

A team of astronomers has used the Low Frequency Receiver onboard the twin Solar Terrestrial Relations Observatory spacecraft to deduce the characteristics of nanodust, showing that this nanometer-scale dust is a significant contributor to the total mass in interplanetary space. In our solar system, dust particles are abundant, created by asteroid collisions and by the […]

Hubble Bubble Helps Explain Differing Measurements for the Expansion Rate of the Universe

Hubble Bubble Simulation

A team of physicists has developed a theoretical model to help explain some of the deviations between previous measurements of the expansion rate of the universe and the latest measurements from the Planck satellite. The existence of the “Hubble Bubble” may explain, at least in part, the differing measurements for the expansion and therefore the […]
