A Giant Gravity Wave Has Been Found in Venus’ Clouds

The 6,200-mile-long structure was observed by Japan’s Akatsuki spacecraft and is believed to be created by mountains on the surface of Venus. Venus is wrapped in thick clouds of sulfuric acid that swirl around the planet at 225 mph, but not everything in the atmosphere is moving.

On Dec. 7, 2015, during its very first orbit around Venus, Japan’s Akatsuki spacecraft discovered a mammoth, bow-shaped structure in the upper atmosphere that remained oddly fixed over a mountainous region known as the western highlands of Aphrodite.

Gravitational Waves to Crack Neutron Star Mystery

As gravitational wave observatories become more sensitive, we may see the collisions of neutron stars and, possibly, find out what these stellar husks are REALLY made of. We are now in an incredible new era of astronomy where the faint ripples in spacetime caused by distant black hole collisions are being detected and studied. These are the most energetic events in the cosmos and, by “listening in” to their gravitational wave signals, these black hole mergers have finally been directly observed.

Gravitational Waves Ripple Through Scientific Community

Newly spotted ripples in space-time are making waves in the scientific community.

The recent announcement of a second gravitational wave detection by the Laser Interferometer Gravitational Wave Observatory (LIGO) has sparked excitement and enthusiasm even among scientists not directly involved in studying these wrinkles in space and time. Space.com spoke with several astronomers at the 228th meeting of the American Astronomical Society (AAS) in San Diego, California, to gauge their reaction.

Gamma-Ray Burst Detected Near Gravitational Wave Source

On Sept. 14, 2015, our planet experienced a very slight spacetime ripple that was detected by the Laser Interferometer Gravitational Wave Observatory (LIGO). On analyzing the signal, physicists realized these gravitational waves were caused by a black hole merger, some 1.3 billion light-years away. This first gravitational wave event was dubbed “GW150914.” Continue reading Gamma-Ray Burst Detected Near Gravitational Wave Source

Hawking: Gravitational Waves Could Revolutionize Astronomy

In the wake of last week’s historic announcement of the discovery of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO), British physicist and black hole theorist Stephen Hawking was quick to congratulate the US-led collaboration, sharing his excitement for the historic news. Continue reading Hawking: Gravitational Waves Could Revolutionize Astronomy

Gravitational Wave Rumors Rumble Social Media

In the roller-coaster rumor mill that surrounds some of the biggest physics endeavors of our time, it pays to remain skeptical when extraordinary claims of historic discoveries are made on social media. In a tweet by Lawrence Krauss this morning, the well-known Arizona State University theoretical physicist and cosmologist wrote: “My earlier rumor about LIGO has been confirmed by independent sources. Stay tuned! Gravitational waves may have been discovered!! Exciting.” Continue reading Gravitational Wave Rumors Rumble Social Media

Electronic ‘ear’ aims to pick up gravitational waves in real time

  • Computer program listens in on Theory of Relativity-inspired search
  • Success measured by ambulance siren-style chirp
  • Gravity waves indicate supernovae and black hole crashes

UWA researchers have developed an electronic ‘ear’ that will vastly improve the ongoing international search for elusive gravitational waves, which are created by violent cosmic events throughout the universe.
