Gravitational waves can be thought of like the sound waves emitted after an earthquake, but the source of the "tremors" in space are energetic events like supernovae (exploding stars), binary neutron stars (pairs of burned-out cores left behind when stars... Continue reading

“The MAVEN science mission focuses on answering questions about where did the water that was present on early Mars go, about where did the carbon dioxide go,” said Bruce Jakosky, MAVEN principal investigator from the University of Colorado, Boulder's Laboratory... Continue reading

Theoretical physicists have theorized a possible solution to a longstanding mystery bolstered by the recent discovery of the Higgs boson – a way to preserve the theory of supersymmetry. It was a breakthrough with profound implications for the world as... Continue reading

Galaxies such as our own Milky Way are believed to form over billions of years through the coming together of many smaller galaxies. As a result, it is expected that there should be many smaller dwarf galaxies scattered around the... Continue reading

“Dark matter is there,” says says Paolo Zuccon, an assistant professor of physics at MIT. “We just don’t know what it is. AMS has the possibility to shine a light on its features. We see some hint now, and it... Continue reading

Massive galaxies in the Universe have stopped making their own stars and are instead cannibalising nearby galaxies, according to research by Australian scientists. Astronomers looked at more than 22,000 galaxies and found that while smaller galaxies were very efficient at... Continue reading

The DNA of every organism on Earth is a right-handed double helix, but why that would be has puzzled scientists since not long after Francis Crick and James Watson announced the discovery of DNA's double-helical structure in 1953. It's a... Continue reading

Astronomers using data from NASA’s Hubble Space Telescope and ground observation have found an unlikely object in an improbable place -- a monster black hole lurking inside one of the tiniest galaxies ever known. “That is pretty amazing, given that... Continue reading

NGC 2683 is a spiral galaxy seen almost edge-on, giving it the shape of a classic science fiction spaceship, which is why the astronomers at the Astronaut Memorial Planetarium and Observatory, Cocoa, Fla., gave it this nickname. This barred spiral... Continue reading

Is dark matter the "operating system" of the Universe? Tom Broadhurst, an Ikerbasque researcher at the UPV/EHU's Department of Theoretical Physics, thinks it is. He has participated alongside scientists of the National Taiwan University in a piece of research that... Continue reading

An international research has made surprising observations that most galaxy collisions in the nearby Universe — within 40 million light-years from Earth — result in so-called disc galaxies. Disc galaxies — including spiral galaxies like the Milky Way and lenticular... Continue reading

“Humankind hasn't had an experience like this--an encounter with a new planet--in a long time,” he Alan Stern, of the Southwest Research Institute and the mission’s principal investigator. “Everything we see on Pluto will be a revelation.” One of the... Continue reading

Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates. This alternate view of Earth’s first geologic eon, called the Hadean,... Continue reading

“If the Sun were less intense, Mercury would be within the habitable zone, and therefore life would have to adapt to strange light cycles,” said Sarah Brown, an astrobiologist at the United Kingdom Center for Astrobiology in Edinburgh, Scotland. Mercury... Continue reading

There is an ongoing drama in the Saturnian ring system that causes small moons to be born and then destroyed on time scales that are but an eyeblink in the history of the solar system. SETI Institute scientists Robert French... Continue reading

Over the history of the Earth, billions of football-sized rocks have landed on its surface, some only slightly heated by the launch, reaching Earth in a matter of a few months. Recent research on lunar rocks discovered in Antarctica has... Continue reading

At a public lecture Einstein gave in Pittsburgh in 1934, four hundred students were present when Einstein mathematically derived his famous mass-energy equivalence equation: E=mc2. This is thought to be the only surviving photo that shows Einstein working on that... Continue reading

Around 12,800 years ago, a sudden, catastrophic event plunged much of the Earth into a period of cold climatic conditions and drought. This drastic climate change—the Younger Dryas—coincided with the extinction of Pleistocene megafauna, such as the saber-tooth cats and... Continue reading

Planet Venus, with its thick atmosphere made of carbon dioxide, its parched surface, and pressures so high that landers are crushed within a few hours, offers scientists a chance to study a planet very foreign to our own. Mysterious holes... Continue reading

Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be produced non-biologically,... Continue reading
Image
Kepler researchers want to understand how terrestrial planets like Venus, Earth and Mars and gas giant planets like Jupiter are distributed in planetary systems around other stars. Understanding how planetary systems form and where different types of planets form can... Continue reading

Quasars are supermassive black holes that live at the center of distant massive galaxies. They shine as the most luminous beacons in the sky across the entire electromagnetic spectrum by rapidly accreting matter into their gravitationally inescapable centers. New work... Continue reading

The question of how massive stars spend their short lives until they become supernovae is of great interest for astrophysicists. According to the standard theory, which is only applicable to isolated stars, only cool and extended (red supergiants) or hot... Continue reading

A new survey of galaxies by NASA's Spitzer Space Telescope is taking a plunge into the deep and uncharted waters of our cosmos. In one of the longest surveys the telescope will have ever performed, astronomers have begun a three-month... Continue reading

"Understanding organic dust is important, because such materials are more resistant to destruction during atmospheric entry, and some could have been delivered intact to the early Earth, thereby fueling the emergence of life,” said Michael Mumma, director of the Goddard... Continue reading
