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.....»»
The Physics of Cold Water May Have Jump-Started Complex Life
When seawater gets cold, it gets viscous. This fact could explain how single-celled ocean creatures became multicellular when the planet was frozen during “Snowball Earth,” according to experiments......»»
Archaeologists conduct first "space excavation" on ISS and discover surprising quirks of zero-G life
New results from the first archaeological fieldwork conducted in space show the International Space Station is a rich cultural landscape where crew create their own "gravity" to replace Earth's, and adapt module spaces to suit their needs......»»
The universe on display: The powerful instruments that allow us to observe the cosmos
Starting today, the Earth will be passing through a meteor shower. But in astronomy, the human eye is very much a limited tool. But increasingly powerful instruments are allowing us to peer ever deeper into the cosmos and ever further back in time, s.....»»

Powering enzymes with light to make ammonia
The Earth's atmosphere contains large amounts of nitrogen in the form of dinitrogen gas (N2). Converting N2 to ammonia (NH3) is critical for making the fertilizer needed for agriculture......»»
Recovery of rocks that originated in Earth"s mantle could reveal secrets of planet"s history

The earliest traces of life on Earth—researchers explore carbon in 3.9-billion-year-old Canadian rocks
The isotopic composition of carbon in iron formations from the Saglek-Hebron Complex in Nunatsiavut (northern Labrador) has been seen as evidence of the earliest traces of life on Earth. But a new study by the University of Ottawa, Carleton Universit.....»»
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»

Astronomers discover two new super-Earths orbiting nearby stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected two new super-Earth exoplanets orbiting nearby M-dwarf stars. The newfound exoplanets, designated TOI-6002 b and TOI-5713 b, are two times la.....»»
Weather "whiplash" in Antarctica may help predict effects of future climate change
The McMurdo Dry Valleys of Antarctica live up to their name. The region is one of the driest places on Earth—mountains form a wall around the valleys and prevent melting glacier water from intruding, humidity is extremely low, and no rain was docum.....»»
New study suggests that our galaxy is crowded or empty—both are equally terrifying
Is there intelligent life in the universe? And if so, just how common is it? Or perhaps the question should be, what are the odds that those engaged in the Search for Extraterrestrial Intelligence (SETI) will encounter it someday?.....»»
July ends 13-month streak of global heat records as El Nino ebbs, but experts warn against relief
Earth's string of 13 straight months with a new average heat record came to an end this past July as the natural El Niño climate pattern ebbed, the European climate agency Copernicus announced Wednesday......»»
