Washington, DC-- NASA's Curiosity rover has discovered new "tough" organic molecules in three-billion-year-old sedimentary rocks on Mars, increasing the chances that the record of habitability and potential life could have been preserved on the Red Planet, despite extremely harsh conditions on the surface that can…

Minerology on Mars points to a cold and icy ancient climate

IMAGE: Researchers expect the volcanoes in Mars' Sisyphi Planum region to look similar to subglacial volcanoes on earth, such as Herðubreið in Iceland. view more  Credit: Purdue University photo/Sheridan Ackiss The climate throughout Mars' early history has long been debated - was the Red Planet warm and wet, or cold and icy? New research published in Icarus provides evidence for the latter. Mars is littered with…

Researchers discover multiple alkali metals in unique exoplanet

The extrasolar planet WASP-127b is one of the least dense exoplanets ever found. It has a radius 1.4 times greater than Jupiter, but only 20% of its mass. Such a planet has no analogue in the solar system and is rare even within the exoplanet diversity. It takes just over four days to complete an orbit around its parent star and its surface temperature is…

The Clarke exobelt, a method to search for possible extraterrestrial civilizations

Finding life in other parts of the universe has been one of humanity's constant dreams. For the first time in history the scientific community has hopes based on some degree of possibility that this dream will become a reality in the not too distant future. This is, in part, due to the new generation of giant telescopes, presently in the planning phase, which we hope…

FEFU scientists have created a new type of optical ceramic material

IMAGE: This is a monophase polycrystal with an average grain size of 500 nm obtained by FEFU scientists, Russia. Because of the innovative method of reaction spark plasma sintering (RSPS) the... view more  Credit: FEFU laboratory Materials Multilayer YAG/Nd3+:YAG/YAG composite laser ceramics with a high concentration of active additive outclassed the commercial glass and single crystals used in laser technologies by it's physical and mechanical characteristics.…

Researchers to Discuss Science Launching on Next Resupply Mission to Space...

NASA will host a media teleconference at 2 p.m. EDT Monday, June 11, to discuss a number of science investigations launching to the International Space Station on the next SpaceX commercial resupply mission.

NASA TV to Air US Spacewalk at International Space Station

NASA astronauts will embark on a six-and-a-half-hour spacewalk Thursday, June 14, during which they will install new high-definition cameras to capture spacecraft docking with the International Space Station, including new American-made spacecraft with scheduled test flights later this year.

Researchers at the IAC participate in the discovery of clusters of...

With observations made with the Herschel Space Observatory, with the APEX antenna and with the ALMA interferometer it has been possible to observe the formation of a cluster of galaxies in deep space, when the Universe was only a tenth as old as it is now. The European Space Agency, ESA, launched the Herschel Space Observatory in 2009. It was the first observatory able to…

NASA peers into the rainfall of Eastern Pacific’ Tropical Storm Aletta

Tropical Storm Aletta is spinning more than 440 miles off the southwestern coast of Mexico and using satellite data, NASA peered into the storm to uncover where the heaviest rain was falling. Early on June 6, Tropical Depression Two-E was upgraded to Tropical Storm Aletta. This is the first tropical storm of the 2018 eastern North Pacific season. Aletta was located well southwest of Mexico.…

The disc of the Milky Way is bigger than we thought

IMAGE: The coloured region is the previously known Galactic disk. The present work has extended its limits much farther away: there is a probability 99.7 percent or 95.4 percent respectively that... view more  Credit: R. Hurt, SSC-Caltech, NASA/JPL-Caltech. Spiral galaxies such as the Milky Way have discs which are really thin, in which the major fraction of their stars are found. These discs are limited in…
