If Earth were an exoplanet, JWST would know there"s an intelligent civilization here
If we're going to look for life on other worlds, why not start with the one planet we know has life? Earth's atmosphere is rich with oxygen and molecules such as methane, which strongly suggest the presence of life. It also has traces of molecules su.....»»
High-pressure reactions can turn nonporous rocks into sponges
In deep Earth, rocks take up and release water all the time, and the effects can be wide reaching. Dehydration can cause rocks to crack and trigger earthquakes, and over geologic timescales, this water cycling can influence plate tectonics and move c.....»»
A Soyuz capsule with 2 Russians and 1 American from the International Space Station returns to Earth
A Soyuz capsule carrying two Russians and one American from the International Space Station landed Monday in Kazakhstan, ending a record-breaking stay for the Russian pair......»»
Could stars hotter than the sun still support life?
Although most potentially habitable worlds orbit red dwarf stars, we know larger and brighter stars can harbor life. One yellow dwarf star, for example, is known to have a planet teaming with life, perhaps even intelligent life. But how large and bri.....»»
Advanced civilizations will overheat their planets within 1,000 years, researchers suggest
Earth's average global temperatures have been steadily increasing since the Industrial Revolution. According to the National Oceanic and Atmospheric Agency (NOAA), Earth has been heating up at a rate of 0.06°C (0.11°F) per decade since 1850—or ab.....»»

A record of the Earth’s temperature covering half a billion years
With one exception, a strong link between carbon dioxide and global temperatures. Enlarge / The cycle of building and breaking up of supercontinents seems to drive long-term climate trends. (credit: Walter Myers/Stocktrek Images).....»»
Citizen science collaboration yields precise data on exoplanet WASP-77 A b
A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets—planets around stars other than the sun. But predicting when these special events occur.....»»
Algorithm used on Mars rover helps scientists on Earth see data in a new way
A new algorithm tested on NASA's Perseverance Rover on Mars may lead to better forecasting of hurricanes, wildfires, and other extreme weather events that impact millions globally......»»
Plants could still grow well under alien skies
Photosynthesis changed Earth in powerful ways. When photosynthetic organisms appeared, it led to the Great Oxygenation Event. That allowed multicellular life to evolve and resulted in the ozone layer. Life could venture onto land, protected from the.....»»
Life might thrive on the surface of Earth for an extra billion years
The sun is midway through its life of fusion. It's about 5 billion years old, and though its life is far from over, it will undergo some pronounced changes as it ages. Over the next billion years, the sun will continue to brighten......»»
Hubble lights the way with new multiwavelength view of galaxy NGC 1559
The magnificent galaxy featured in this NASA/ESA Hubble Space Telescope image is NGC 1559. It is a barred spiral galaxy located in the constellation Reticulum, approximately 35 million light-years from Earth. The brilliant light captured in the curre.....»»

Scientists scan TRAPPIST-1 for technosignatures
If you are going to look for intelligent life beyond Earth, there are few better candidates than the TRAPPIST-1 star system. It isn't a perfect choice. Red dwarf stars like TRAPPIST-1 are notorious for emitting flares and hard X-rays in their youth,.....»»
Don"t overlook microorganisms" role in planet health, scientists warn
The tiniest and oldest creatures on—and in—Earth have a huge role in achieving a sustainable future for the planet, an international team of scientists, including faculty researchers from The Ohio State University, asserts in a new Cell article p.....»»
Visible-light-antenna ligand enhances samarium-catalyzed reactions
Samarium (Sm), a rare earth metal, is important to organic chemists because of the ability of its divalent compounds to efficiently perform single-electron transfer reductions......»»
NASA watches a peanut-shaped asteroid drift past Earth
Peanuts! Get your peanuts here! The solar system has been passing out peanuts lately in the form of two different oddly shaped asteroids that recently passed by Earth, and both look like over-sized peanuts......»»
Explaining dramatic planetwide changes after world"s last "Snowball Earth" event
Some of the most dramatic climatic events in our planet's history are "Snowball Earth" events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles (1 kilometer) thick......»»
Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the atmospheres of exoplanets,.....»»
New research re-envisions Earth"s mantle as a relatively uniform reservoir
Lavas from hotspots—whether erupting in Hawaii, Samoa or Iceland—likely originate from a worldwide, uniform reservoir in Earth's mantle, according to an evaluation of volcanic hotspots published in Nature Geoscience......»»
Geoscientists confirm "dripping" of Earth"s crust beneath Türkiye"s Central Anatolian Plateau
Recent satellite data reveal that the Konya Basin in the Central Anatolian Plateau of Türkiye is continually being reshaped over millions of years, according to a new analysis led by Earth scientists at the University of Toronto......»»
