"For a long time, we've been looking into space to try and find a pair of these supermassive black holes orbiting as a result of two galaxies merging," said Greg Taylor at the University of New Mexico. "Even though we've theorized that this should be happening, nobody had ever seen it until now." While the technical accomplishment of this discovery is truly amazing, the research could also teach us a lot about the universe, where galaxies come from and where they're going.

China's 1st Space Observatory Powers Up X-Ray Detectors That Will Scan the Milky Way to Map Black Holes and Neutron Stars (WATCH Video)

 

Pia20027_updated


The main detectors on China's first space observatory, the Hard X-ray Modulation Telescope (HXMT), have been powered up as the satellite enters a period of on-orbit testing to collect highly energetic x-rays emitted by black holes, neutron stars and other phenomena across a range of 1-250 kiloelectron volts (keV). Zhang Shuangnan, principal investigator of the project with China's Institute of High Energy Physics, says that HXMT will survey the Galactic plane to create a high precision x-ray map of the sky.

"Uranus is a geometric nightmare," said Carol Paty, the Georgia Tech associate professor who co-authored the study. "The magnetic field tumbles very fast, like a child cartwheeling down a hill head over heels. When the magnetized solar wind meets this tumbling field in the right way, it can reconnect and Uranus' magnetosphere goes from open to closed to open on a daily basis."

ESA's Gaia Space Telescope Mimics the Human Brain --"Reveals Some of the Most Obscure Regions of the Milky Way" (VIDEO)

Our galactic home, the Milky Way, houses more than a hundred billion stars, all kept together by gravity. Most are located in a flattened structure – the galactic disc – with a bulge at its center, while the remaining stars are distributed in a wider spherical halo extending out to about 650 000 light-years from the center. With the help of software that mimics a human brain, ESA's Gaia satellite spotted six stars zipping at high speed from the center of our galaxy to its outskirts. This could provide key information about some of the most obscure regions of the Milky Way.

Milky Way's 'Dark-Matter' Anomaly --"Explains Why Our Galaxy Appears to be Special"

 

 

 

Milky-Way-s-Dark-Matter-Disk-Can-t-Be-Found-2


In the enchanting night sky, with myriad galaxies and stars, what we see is only about 20% of all the matter in the Universe. The remaining is in the form of a non-luminous and exotic form of matter that we know little about. This so-called dark matter has been the object of intense scientific exploration in the last few decades. According to many popular theories, dark matter particles annihilate at the same rate in both small and large astronomical bodies and at all times in the Universe.

During its journey, Cassini has made many discoveries, including a global ocean with hydrothermal activity within Saturn's moon Enceladus, and vast seas of liquid methane on the planet's largest moon, Titan. Cassini began the final, dramatic phase of its mission, called the Grand Finale, on April 26, with the first of planned 22 dives between Saturn and its rings. The finale orbits bring the spacecraft closer to Saturn than ever before, providing stunning, high-resolution images and new insights into the planet's interior structure and the origins of the rings. During its final plunge into Saturn, Cassini will send data about the atmosphere's composition until its signal is lost.
