Astronomers detect extended dark matter halo around ancient dwarf galaxy
Boston MA (SPX) Feb 02, 2021
The Milky Way is surrounded by dozens of dwarf galaxies that are thought to be relics of the very first galaxies in the universe. Among the most primitive of these galactic fossils is Tucana II - an ultrafaint dwarf galaxy that is about 50 kiloparsecs, or 163,000 light years, from Earth.
Now MIT astrophysicists have detected stars at the edge of Tucana II, in a configuration that is surpri

Searching for dark matter through the fifth dimension
Mainz, Germany (SPX) Feb 02, 2021
Theoretical physicists of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz are working on a theory that goes beyond the Standard Model of particle physics and can answer questions where the Standard Model has to pass - for example, with respect to the hierarchies of the masses of elementary particles or the existence of dark matter.
The central element of the theory

Backreaction observed for first time in water tank black hole simulation
Nottingham UK (SPX) Feb 02, 2021
Scientists have revealed new insights into the behaviour of black holes with research that demonstrates how a phenomenon called backreaction can be simulated.
The team from the University of Nottingham have used their simulation of a black hole, involving a specially designed water tank, for this latest research published in Physical Review Letters. This study is the first to demonstrate t

Study reveals MESSENGER watched a meteoroid strike Mercury
Laurel MD (SPX) Feb 02, 2021
NASA's MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) mission to Mercury has been out of operation for nearly six years, but the data it collected keeps on giving, from revealing new insights about Venus' atmosphere to providing a new way to measure the length of time neutrons can survive on their own.

Could the surface of Phobos reveal secrets of the Martian past
Greenbelt MD (SPX) Feb 02, 2021
The Martian moon Phobos orbits through a stream of charged atoms and molecules that flow off the Red Planet's atmosphere, new research shows.
Many of these charged particles, or ions, of oxygen, carbon, nitrogen, and argon, have been escaping Mars for billions of years as the planet has been shedding its atmosphere. Some ions, scientists predict, have been smashing into the surface of Phob

NASA will pay $500,000 for good ideas on food production in space
Washington DC (UPI) Feb 1, 2021
NASA is prepared to pay $500,000 for a good idea to help feed astronauts on long-term space missions with something other than dried, packaged food from Earth.
The space agency has set a July 30 deadline on its Deep Space Food Challenge, when it will choose a winning idea. The Canadian Space Agency launched a similar challenge with phased awards totaling $500,000 that will result in a g

NASA completes spacewalk to finish power system upgrades
Washington DC (UPI) Feb 1, 2021
Two NASA astronauts completed a major upgrade to the orbiting platform's power systems and other tasks during a spacewalk on Monday.
The project began at 6:56 a.m. EST and lasted for five hours and 20 minutes. The expedition was the second spacewalk in five days for Michael Hopkins and Victor Glover.
"You guys had a great day. You guys rocked it," astronaut Bob Hines said from gr

Businessman plans first all-civilian SpaceX flight to benefit St. Jude's hospital
Washington DC (UPI) Feb 1, 2021
SpaceX announced plans on Monday for the first all-civilian mission to space in late 2021 - a days long orbit of the Earth, to be led by finance company executive and pilot Jared Isaacman.
Isaacman has purchased a four-person mission in the SpaceX Dragon capsule Resilience to launch atop a Falcon 9 rocket from Florida. He expects a mission duration ranging from two to four days.
