NASA infrared imagery shows a powerful Tropical Cyclone Marcus

IMAGE: On March 20 at 2:35 a.m. EDT (0635 UTC) the MODIS instrument aboard NASA's Aqua satellite found top temperatures of strongest thunderstorms (yellow) in Tropical Cyclone Marcus Temperatures were as... view more  Credit: Credits: NRL/NASA Tropical Cyclone Marcus continues to strengthen as it moves further away from Western Australia. NASA's Aqua satellite analyzed the system in infrared light to find the strongest part of the…

A star disturbed the comets of the solar system in...

About 70,000 years ago, when the human species was already on Earth, a small reddish star approached our solar system and gravitationally disturbed comets and asteroids. Astronomers from the Complutense University of Madrid and the University of Cambridge have verified that the movement of some of these objects is still marked by that stellar encounter. At a time when modern humans were beginning to leave…

TRAPPIST-1 planets provide clues to the nature of habitable worlds

IMAGE: This is a slice through a model composition of TRAPPIST-1 'f' which contains over 50 percent water by mass. The pressure of the water alone is enough to cause it... view more  Credit: ASU TRAPPIST-1 is an ultra-cool red dwarf star that is slightly larger, but much more massive, than the planet Jupiter, located about 40 light-years from the Sun in the constellation Aquarius. Among…

NASA to Preview Upcoming US Spacewalk, Provide Live Coverage

Two American astronauts will venture outside the International Space Station on Thursday, March 29, for a planned 6.5-hour spacewalk. Experts from NASA will preview this work in a briefing at 2 p.m. EDT Tuesday, March 27, at NASA’s Johnson Space Center in Houston.

‘Oumuamua likely came from a binary star system

New research finds that 'Oumuamua, the rocky object identified as the first confirmed interstellar asteroid, very likely came from a binary star system. "It's remarkable that we've now seen for the first time a physical object from outside our Solar System," says lead author Dr Alan Jackson, a postdoc at the Centre for Planetary Sciences at the University of Toronto Scarborough in Ontario, Canada. A…

VIIRS satellite instrument gets 2 views of Tropical Cyclone Marcus

IMAGE: On March 18, 2018 the VIIRS instrument aboard Suomi NPP captured a true-color image of Marcus. At the time of the image, according to the Joint Typhoon Warning Center, Marcus... view more  Credit: Credits: NOAA/NASA Rapid Response Team Tropical Cyclone Marcus was moving along the northern coast of Australia when the VIIRS instrument that flies aboard two different satellites captured true-color images of the storm…

NASA analyzes Tropical Cyclone Eliakim’s rainfall, wind shear now affecting storm

Tropical Cyclone Eliakim soaked the eastern coast of Madagascar as it moved in a southerly path. NASA analyzed that rainfall using data from the Global Precipitation Measurement mission or GPM core satellite. Another NASA satellite provided a current look at the storm that revealed wind shear was taking a toll on the storm. Tropical cyclone Eliakim's heavy rainfall caused flooding and landslides over eastern Madagascar…

CAMBRIDGE, MASS. -- On Nov. 11, 2014, a global network of telescopes picked up signals from 300 million light years away that were created by a tidal disruption flare - an explosion of electromagnetic energy that occurs when a black hole rips apart a passing star. Since this discovery, astronomers have trained other telescopes on this very rare event to learn more about how black…

Cosmologists create largest simulation of galaxy formation, break their own record
