Making planets in a rocket
Nov 18, 2019 (ESA)
Astronomers conclude that planets are formed out of cosmic dust and gas from an interstellar cloud around a new-born star, but exactly how dust particles start ...
Scientists use 3D climate model to narrow search for habitable exoplanets
Nov 14, 2019 (UPI)
The findings -- published Thursday in the Astrophysical Journal -- could help planetary scientists know what to look for when surveying potentially habitable ex...
Distant worlds under many suns
Nov 14, 2019 (SPX)
More than 4,000 exoplanets are known to date, most of them orbiting single stars like our Sun. Now astrophysicist Dr Markus Mugrauer of Friedrich Schiller Unive...
Study refines which exoplanets are potentially habitable
Nov 12, 2019 (SPX)
The research team is the first to combine 3D climate modeling with atmospheric chemistry to explore the habitability of planets around M dwarf stars, which comp...
Life on Venus and the interplanetary transfer of biota from Earth
Nov 11, 2019 (SPX)
Life on Venus? Is that possible? Dozens of scientists think so, including Carl Sagan and former NASA scientist, David Grinspoon, who proposed almost twenty year...
NASA instrument to probe planet clouds on European mission
Nov 11, 2019 (JPL)
The instrument, called the Contribution to ARIEL Spectroscopy of Exoplanets, or CASE, adds scientific capabilities to ESA's (the European Space Agency's) Atmosp...
The most spectacular celestial vision you'll never see
Nov 06, 2019 (SPX)
What's more, the view from that Earth-like planet as its giant neighbor moves past would be unlike anything it is possible to view in our own night skies on Ear...
Deep sea vents had ideal conditions for origin of life
Nov 05, 2019 (SPX)
Previous experiments had failed to foster the formation of protocells - seen as a key stepping stone to the development of cell-based life - in such environment...
Worldwide observations confirm nearby 'lensing' exoplanet
Nov 03, 2019 (SPX)
The results of this research suggest that Neptune-sized planets could be common around this orbital region. Because the exoplanet discovered this time is closer...
A new spin on life's origin?
Nov 03, 2019 (SPX)
By gradually removing the solvent from a rotating solution containing non-chiral precursors, they were able to produce helixes that twist preferentially in a pa...
Even 'goldilocks' exoplanets need a well-behaved star
Nov 01, 2019 (SPX)
Lead author and Rice graduate student Alison Farrish and her research adviser, solar physicist David Alexander, led their group's first study to characterize th...
Simulations explain giant exoplanets with eccentric, close-in orbits
Oct 31, 2019 (SPX)
Surprisingly, the planets with the highest masses tend to be those with the highest eccentricities, even though the inertia of a larger mass should make it hard...
TESS reveals an improbable planet
Oct 30, 2019 (SPX)
Tiago Campante (IA and Faculdade de Ciencias da Universidade do Porto - FCUP) explains that detecting these oscillations was only possible because: "TESS observ...
Breakthrough Listen to collaborate with scientists from NASA's TESS Team
Oct 24, 2019 (SPX)
The new collaboration will be led by TESS Deputy Science Director, MIT Professor Sara Seager; S. Pete Worden, Executive Director of the Breakthrough Initiatives...
Building blocks of all life gain new understanding
Oct 24, 2019 (SPX)
The work gives a structural understanding of how a light activated enzyme involved in chlorophyll synthesis works. Light activated enzymes are rare in nature, w...
With NASA telescope on board, search for intelligent aliens 'more credible'
Oct 24, 2019 (AFP)
So has alien hunting finally earned its stripes as a scientific discipline? To find out, AFP spoke to scientist Jill Tarter who has devoted her life to searchin...
When Exoplanets Collide
Oct 23, 2019 (SPX)
Known as BD +20 307, this double-star system is more than 300 light years from Earth with stars that are at least one billion years old. Yet this mature system ...
Planetary Protection Review addresses changing reality of space exploration
Oct 19, 2019 (SPX)
With NASA, international, and commercial entities planning bold missions to explore our solar system and return samples to Earth, the context for planetary prot...
Ancient microbes are living inside Europe's deepest meteorite crater
Oct 18, 2019 (UPI)
Some 400 million years ago, a massive space rock slammed into northern Europe, excavating a giant crater in the middle of what's now Sweden. Today, prospectors ...
Cascades of gas around young star indicate early stages of planet formation
Oct 17, 2019 (SPX)
In their youth, stars are surrounded by a rotating disk of gas and dust from which planets are born. Studying the behavior of the material that makes up these d...
