Unexpected rain on sun links two solar mysteries For five months in mid 2017, Emily Mason did the same thing every day. Arriving to her office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, she sat at her desk, opened up her computer, and stared at images of the Sun—all day, every day. “I probably looked through three or five years’ worth of data,” Mason estimated. Then, in October 2017, she stopped. She realized she had been looking at the wrong thing all along. phys.org Go to SourceRead More →
Gravitational waves helping to expose black holes, dark matter and theoretical particles Gravitational waves – the invisible ripples in the fabric of space predicted by Albert Einstein – are opening up a new era of astronomy that is allowing scientists to see parts of the universe once thought to be invisible, such as black holes, dark matter and theoretical subatomic particles called axions. phys.org Go to SourceRead More →
Gamma-ray blazars in the sky When the supermassive black holes at the center of galaxies accrete material, they can eject powerful jets of charged particles at speeds approaching that of light. These particles in turn emit radiation across the electromagnetic spectrum, from radio to gamma-rays. When the jets happen to be aligned toward the Earth, these objects are called blazars, and in a flare they can emit as much radiation as a million billion suns. phys.org Go to SourceRead More →
Mars Express Saw the Same Methane Spike that Curiosity Detected from the Surface of Mars If you’re not a chemist, an astrobiologist, or a scientist of any sort, and that includes most of us, then a tiny, almost imperceptible whiff of methane in the Martian atmosphere might seem like no big deal. But it is, gentle humans. It is. Why? Because it could be a signal that some living process … Continue reading “Mars Express Saw the Same Methane Spike that Curiosity Detected from the Surface of Mars” The post Mars Express Saw the Same Methane Spike that Curiosity Detected from the Surface of MarsRead More →

Heavy metal planet fragment survives destruction from dead star A fragment of a planet that has survived the death of its star has been discovered by University of Warwick astronomers in a disc of debris formed from destroyed planets, which the star ultimately consumes. phys.org Go to SourceRead More →
AstroSAT observations reveal quasi-periodic oscillations in the X-ray binary GX 5-1 Using the AstroSAT spacecraft, Indian astronomers have observed the low-mass X-ray binary designated GX 5-1. The observations were published March 28 on the arXiv pre-print repository. The authors report the detection of quasi-periodic oscillations in this binary and discuss its nature. phys.org Go to SourceRead More →

Mars Helicopter Completes More Test Flights. It’s Almost Ready to go to Mars We’ve known for some time that NASA is sending a helicopter to Mars. The vehicle, called the Mars Helicopter, is undergoing flight testing at NASA’s Jet Propulsion Laboratory in California. The little helicopter will make its eventual way to Mars as part of the Mars 2020 Rover mission. The Mars Helicopter is pretty small, less … Continue reading “Mars Helicopter Completes More Test Flights. It’s Almost Ready to go to Mars” The post Mars Helicopter Completes More Test Flights.

See the Moon Photobomb Saturn in an Amazing Capture It’s always awe-inspiring to see the clockwork motion of the heavens, transpire in real time. In a slow motion Universe, occultations give us the chance to see the cosmos pull off a celestial hat trick. This happen in a blink of an eye type event such as when the Moon, a planet or an asteroid winks out a distant star, or transpire as a leisurely affair as the Moon covers, then uncovers the disk of a planet.
