"Titan's extreme physical environment requires scientists to think differently about what we've learned of Earth's granular dynamics," said Josef Dufek, with the Georgia Institute of Technology. "Landforms are influenced by forces that aren't intuitive to us because those forces aren't...
(ESO) Observations using ESO's Very Large Telescope have revealed stars forming within powerful outflows of material blasted out from supermassive black holes at the cores of galaxies. These are the first confirmed observations of stars forming in this kind of extreme environment. Show More Summary
The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the Sun, according to a new study led by a scientist at the National Center for Atmospheric Research (NCAR). Just...
(National Center for Atmospheric Research/University Corporation for Atmospheric Research) The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the sun, according to a new study led by a scientist at NCAR.
"The possibility that a large ocean once occupied the Martian northern plains is one of the most important and controversial hypotheses to have originated from the exploration of Mars," the researchers wrote in the study. "We mapped lobate deposits, which...
"This is a challenging experiment because we're having to look through a foreground — namely, the Milky Way galaxy — that is at least four orders of magnitude brighter than the signal that we're trying to detect," said Jack Burns,...
(Phys.org)—A team of Indian astronomers has recently studied a peculiar binary system designated PDS 11, revealing new insights into the nature of its stars. The findings, presented Mar. 17 in a paper published on arXiv.org, allowed the researchers to reclassify PDS 11 as an old, dusty, wide binary classical T Tauri system in which both components are actively accreting.
(Phys.org)—A team of researchers with members from France, Italy and the U.S. has found what they believe is evidence of a giant tsunami occurring on Mars approximately 3 billion years ago due to an asteroid plunging into an ocean. In...Show More Summary
Recent research has suggested the weird orbit of the icy worlds Sedna and six others could be explained if there is a Neptune sized object lurking at the very fringes of the solar system. This would be an amazing find. Unlike the discovery...Show More Summary
There's no verdict quiet yet on the giant planet's core, and scientists are still gathering clues about the accuracy of our current solar system formation models.
As you probably know, NASA recently announced plans to send a mission to Jupiter's moon Europa. If all goes well, the Europa Clipper will blast off for the world in the 2020s, and orbit the icy moon to discover all its secrets.
Engineers carried out a critical hot fire engine test firing with the first new engine controlling 'brain' that will command the shuttle-era liquid fueled engines powering the inaugural mission of NASA's new Space Launch System (SLS) megarocket.
At 10:49pm Western Australian time on February 2 this year, cosmic gamma rays hit the NASA satellite, Swift, orbiting the Earth.
Some galaxies are harder to classify than others. Here, Hubble's trusty Wide Field Camera 3 (WFC3) has captured a striking view of two interacting galaxies located some 60 million light-years away in the constellation of Leo (The Lion). Show More Summary
NASA has selected a science mission that will measure emissions from the interstellar medium, which is the cosmic material found between stars. This data will help scientists determine the life cycle of interstellar gas in our MilkyShow More Summary
ESA's ExoMars rover (foreground) and Russia's stationary surface science platform (background) are scheduled for launch in July 2020, arriving at Mars in March 2021. The Trace Gas Orbiter, which has been at Mars since October 2016, will act as a relay station for the mission, as well as conducting its own science mission.
Information from ESA's magnetic field Swarm mission has led to the discovery of supersonic plasma jets high up in our atmosphere that can push temperatures up to almost 10 000°C.
When a star like our sun gets to be very old, after another seven billion years or so, it will shrink to a fraction of its radius and become a white dwarf star, no longer able to sustain nuclear burning. Studying the older planetary systems around white dwarfs provides clues to the long-term fate of our Sun and its planetary system. Show More Summary
ANU is launching a search for a new planet in our solar system, inviting anyone around the world with access to the Internet to help make the historic discovery.
The Australian Space Weather Service (SWS ) has issued a Geomagnetic Warning for 27-28 March UT from a high speed solar wind stream from a large coronal hole with active to minor storm activity predicted. However, the indices are favorable...Show More Summary
