First building blocks of life on Earth was a big mess
Jan 23, 2020 (SPX)
Life is built with three major components: RNA and DNA - the genetic code that, like construction managers, program how to run and reproduce cells - and protein...
Astronomers find a way to form 'fast and furious' planets around tiny stars
Jan 23, 2020 (SPX)
As published in Astronomy and Astrophysics Journal, Dr Anthony Mercer and Dr Dimitris Stamatellos' new planet formation research challenges our understanding of...
Astronomers reveal interstellar thread of one of life's building blocks
Jan 17, 2020 (SPX)
"Life appeared on Earth about 4 billion years ago, but we still do not know the processes that made it possible," says Victor Rivilla, the lead author of a new ...
Cosmic origins of phosphorus, a building block for life, traced by scientists
Jan 15, 2020 (UPI)
The new research, published Wednesday in the journal Monthly Notices of the Royal Astronomical Society, also showed how phosphorus is carried by comets. Scienti...
Cold Neptune and 2 temperate Super-Earths found orbiting nearby stars
Jan 15, 2020 (SPX)
The two potentially habitable planets are orbiting GJ 180 and GJ 229A, which are among the nearest stars to our own Sun, making them prime targets for observati...
Telescope upgrade, move will aid in search for exoplanets
Jan 13, 2020 (SPX)
Dmitry Savransky, assistant professor of mechanical and aerospace engineering, is a co-investigator on a $2.6 million National Science Foundation grant aiming t...
Goldilocks stars are best places to look for life
Jan 09, 2020 (SPX)
An emerging idea, bolstered by a three-decade-long set of stellar surveys, is that there are "Goldilocks stars" - not too hot, not too cool, and above all, not ...
A new tool for 'weighing' unseen planets
Jan 09, 2020 (JPL)
NEID recently made its first observations on the WIYN 3.5-meter (11.5-foot) telescope at Kitt Peak National Observatory when it studied 51 Pegasi, which in 1995...
Planet WASP-12b is on a death spiral
Jan 09, 2020 (SPX)
A Princeton-led team of astrophysicists has shown that WASP-12b is spiraling in toward its host star, heading toward certain destruction. Their paper appears in...
SDSU astronomers pinpoint two new 'Tatooine' planetary systems
Jan 08, 2020 (SPX)
On behalf of the international team of 60 investigators, the work was presented by researcher Veselin Kostov at the 235th meeting of the American Astronomical S...
Technique could speed search for life in outer space
Jan 07, 2020 (SPX)
One possible indication of life, or biosignature, is the presence of oxygen in an exoplanet's atmosphere. Oxygen is generated by life on Earth when organisms su...
New technique may give Webb Telescope new way to identify planets with oxygen
Jan 07, 2020 (SPX)
Since planets around other stars (exoplanets) are so far away, scientists cannot look for signs of life by visiting these distant worlds. Instead, they must use...
TESS mission uncovers its first world with two stars
Jan 07, 2020 (SPX)
"I was looking through the data for everything the volunteers had flagged as an eclipsing binary, a system where two stars circle around each other and from our...
NASA planet hunter finds its first Earth-Size habitable-zone world
Jan 07, 2020 (SPX)
TOI 700 d is one of only a few Earth-size planets discovered in a star's habitable zone so far. Others include several planets in the TRAPPIST-1 system and othe...
Life may have first emerged in phosphorous-rich lakes
Dec 30, 2019 (UPI)
In a new study, published Monday in the journal PNAS, scientists provide evidence that ancient soda lakes could have provided sufficient levels of phosphorous t...
A real-life deluminator for spotting exoplanets by reflected starlight
Dec 27, 2019 (SPX)
For the last decade or more, Muggles around the world - including me - have been busy designing and perfecting a similar device called a coronagraph. It blocks ...
Massive gas disk raises questions about planet formation theory
Dec 24, 2019 (SPX)
Planets are formed in gaseous dusty disks called protoplanetary disks around young stars. Dust particles aggregate together to form Earth-like planets or to bec...
Researchers spy on planets as fluffy as cotton candy
Dec 20, 2019 (SPX)
As their confectionary name suggests, these planets are as lightweight as cotton candy - literally. The fluffy globes are the lowest density exoplanets ever dis...
Europe's exoplanet hunter set for blast-off from Earth
Dec 18, 2019 (AFP)
The 30-centimetre (12-inch) telescope has been designed to measure the density, composition, and size of numerous planets beyond our solar system -- so-called e...
Europe's exoplanet hunter reaches orbit around Earth
Dec 18, 2019 (AFP)
The telescope will measure the density, composition and size of planets beyond our Solar System -- known as exoplanets. According to the European Space Agency (...
