The ‘Star In A Jar’ Technology That Could Change Our World Forever

The process inside of our sun converts hydrogen into helium, which creates an overwhelming amount of energy unparalleled by any human technologies (nuclear fusion). If we could harness this process, our entire outlook on civilization could change - from energy dependency issues, to energy effecincy problems such as deep space travel. For quite some time scientists [...]

New Weather Satellite Sends First Images of Earth

The release of the first images today from NOAA’s newest satellite, GOES-16, is the latest step in a new age of weather satellites. This composite color full-disk visible image is from 1:07 p.m. EDT on Jan. 15, 2017, and was created using several of the 16 spectral channels available on the GOES-16 Advanced Baseline Imager [...]

Earth And The Moon Seen From Saturn

NASA's Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away. MESSENGER, the first probe to orbit Mercury, took a black-and-white image from a distance of 61 million miles (98 million kilometers) as part of a campaign to search [...]

Mysterious X-Ray Signal Intrigues Astronomers

A mysterious X-ray signal has been found in a detailed study of galaxy clusters using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. One intriguing possibility is that the X-rays are produced by the decay of sterile neutrinos, a type of particle that has been proposed as a candidate for dark matter. While holding exciting potential, [...]

Scientists Enter Eight Month Dome In Hawaii Mars Space Mission Study

(Reuters) - Six scientists have entered a dome perched atop a remote volcano in Hawaii where they will spend the next eight months in isolation to simulate life for astronauts traveling to Mars, the University of Hawaii said. The study is designed to help NASA better understand human behavior and performance during long space missions [...]

X-Ray Echoes Of A Shredded Star Provide Close-Up of ‘Killer’ Black Hole

Some 3.9 billion years ago in the heart of a distant galaxy, the intense tidal pull of a monster black hole shredded a star that passed too close. When X-rays produced in this event first reached Earth on March 28, 2011, they were detected by NASA's Swift satellite, which notified astronomers around the world. Within [...]

Black Hole Makes Material Wobble Around It

The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole. The discovery, aided by NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, solves a mystery that has eluded astronomers for more than 30 years, and will allow them to map the behavior of matter very close [...]

NASA’s WISE, Fermi Missions Reveal A Surprising Blazar Connection

Astronomers studying distant galaxies powered by monster black holes have uncovered an unexpected link between two very different wavelengths of the light they emit, the mid-infrared and gamma rays. The discovery, which was accomplished by comparing data from NASA’s Wide-field Infrared Survey Explorer (WISE) and Fermi Gamma-ray Space Telescope, has enabled the researchers to uncover dozens [...]

NASA’s Fermi Finds Record-Breaking Binary In Galaxy Next Door

Using data from NASA's Fermi Gamma-ray Space Telescope and other facilities, an international team of scientists has found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system, dubbed LMC P3, contains a massive star and a crushed stellar core that interact to produce a cyclic flood of [...]

Starvation Diet For Black Hole Dims Brilliant Galaxy

Astronomers may have solved the mystery of the peculiar volatile behavior of a supermassive black hole at the center of a galaxy. Combined data from NASA’s Chandra X-ray Observatory and other observatories suggest that the black hole is no longer being fed enough fuel to make its surroundings shine brightly. Many galaxies have an extremely [...]
