South Africa's new radio telescope reveals giant outbursts from binary star system

Tweet

An international team of astronomers have reported the first scientific results from the Karoo Array Telescope (KAT-7) in South Africa, the pathfinder radio telescope for the $3 billion global Square Kilometre Array (SKA) project.

The results appear in the latest issue of the prestigious international astronomical journal Monthly Notices of the Royal Astronomical Society (MNRAS).

NASA completes first part of Webb Telescope's 'eye surgery' operation

Tweet

Much like the inside of an operating room, in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., engineers worked meticulously to implant part of the eyes of the James Webb Space Telescope. They scrubbed up and suited up to perform one of the most delicate performances of their lives. That part of the eyes, the MIRI, or Mid-Infrared Instrument, will glimpse the formation of galaxies and see deeper into the universe than ever before.

HiRISE Mars camera reveals hundreds of impacts each year

Tweet

Scientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across.

Researchers have identified 248 new impact sites on parts of the Martian surface in the past decade, using images from the spacecraft to determine when the craters appeared. The 200-per-year planetwide estimate is a calculation based on the number found in a systematic survey of a portion of the planet.

NASA satellites eye Cyclone Mahasen as Bangladesh prepares for landfall

Tweet

Tropical Cyclone Mahasen has been strengthening and expanding as it moves through the northern Bay of Bengal for a landfall on Thursday, May 16. NASA's Aqua satellite passed over the cyclone as it was hugging the central India coastline. Rainfall data from NASA's TRMM satellite was compiled in an animation to reveal large rainfall totals as the storm tracked through the Bay of Bengal earlier this week.

NASA sees first Eastern Pacific tropical depression to open season

Tweet

The Hurricane Season of the Eastern Pacific Ocean officially begins today, May 15 and the first tropical depression of the season formed. Tropical Depression One-E was seen by NASA's Aqua satellite while it was developing.

Black hole powered jets plow into galaxy

Tweet

This composite image of a galaxy illustrates how the intense gravity of a supermassive black hole can be tapped to generate immense power. The image contains X-ray data from NASA's Chandra X-ray Observatory (blue), optical light obtained with the Hubble Space Telescope (gold) and radio waves from the NSF's Very Large Array (pink).

Nanotechnology could help fight diabetes

CAMBRIDGE, MA -- Injectable nanoparticles developed at MIT may someday eliminate the need for patients with Type 1 diabetes to constantly monitor their blood-sugar levels and inject themselves with insulin.

High-testosterone competitors more likely to choose red

Tweet

Why do so many sports players and athletes choose to wear the color red when they compete? A new study to be published in Psychological Science, a journal of the Association for Psychological Science, suggests that it may have to do with their testosterone levels.

The new study, conducted by psychological scientist Daniel Farrelly of the University of Sunderland and colleagues, demonstrated that males who chose red as their color in a competitive task had higher testosterone levels than other males who chose blue.

Billion-year-old water could hold clues to life on Earth and Mars

Tweet

A UK-Canadian team of scientists has discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life.

This water could be some of the oldest on the planet and may even contain life. Not just that, but the similarity between the rocks that trapped it and those on Mars raises the hope that comparable life-sustaining water could lie buried beneath the red planet's surface.
