Astronomers investigate the curious case of PDS 11 binary system

(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.

Evidence of giant tsunami on Mars suggests an early ocean

(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

What about a mission to Titan?

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.

NASA test fires new engine controlling 'brain' for first SLS megarocket mission

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.

Something big exploded in a galaxy far, far away—what was it?

At 10:49pm Western Australian time on February 2 this year, cosmic gamma rays hit the NASA satellite, Swift, orbiting the Earth.

Image: Hubble spots two interacting galaxies defying cosmic convention

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 selects mission to study churning chaos in the Milky Way and beyond

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

Image: ESA's ExoMars rover and Russia's stationary surface science platform

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.

Supersonic plasma jets discovered

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.

The fate of exomoons

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

Citizen search for new planet in solar system

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.

Sunrise II: A second look at the Sun

scillating fibrils, explosive increases in temperature, and the footprints of coronal loops: 13 articles published today provide an overview of the results of the second flight of the balloon-borne solar observatory Sunrise.

Juno spacecraft set for fifth Jupiter flyby

NASA's Juno spacecraft will make its fifth flyby over Jupiter's mysterious cloud tops on Monday, March 27, at 1:52 a.m. PDT (4:52 a.m. EDT, 8:52 UTC).

Spacewalk a success for French, US astronauts

A French and an American astronaut floated outside the International Space Station Friday on a successful spacewalk to upgrade the orbiting outpost for the arrival of future space crews.

Extreme space weather: Protecting our critical infrastructure

Extreme space weather has a global footprint and the potential to damage critical infrastructure on the ground and in space. A new report from the European Commission's Joint Research Centre (JRC) calls for bridging knowledge gaps and for better coordination at EU level to reduce the potential impact of space weather events.

OSIRIS-REx asteroid search tests instruments, science team

During an almost two-week search, NASA's OSIRIS-REx mission team activated the spacecraft's MapCam imager and scanned part of the surrounding space for elusive Earth-Trojan asteroids—objects that scientists believe may exist in one of the stable regions that co-orbits the sun with Earth.

Game-changing balloon technology enables near-global flight

After over 20 years of tests and development, NASA's Balloon Program team is on the cusp of expanding the envelope in high-altitude, heavylift ballooning with its super pressure balloon (SPB) technology. SMD technology investments that...Show More Summary

Astronomers identify purest, most massive brown dwarf

An international team of astronomers has identified a record breaking brown dwarf (a star too small for nuclear fusion) with the 'purest' composition and the highest mass yet known. The object, known as SDSS J0104+1535, is a member of the so-called halo – the outermost reaches - of our Galaxy, made up of the most ancient stars. Show More Summary
