Pulsars are one of the more intriguing objects in the sky, radiating regular flashes of electromagnetic energy, which can (sometimes) be seen from Earth. Flashing with astonishing regularity, these objects are stellar corpses of massive stars that met their demise in supernovae. When beams of energy are aligned just right, they can be seen from Earth as regular pulses of light. Occasionally, pulsars produce unpredictable giant radio pulses (GRPs) — short-lived bursts of energy far more powerful than the flashes coming from the stellar corpse itself. New observations show X-ray emissions from the pulsar at the heart of the Crab…This story continues at The Next Web

Until just a century ago, our galaxy was thought to be the lone family of stars occupying the Cosmos. Philosophers, notably Immanuel Kant in the 18th Century, postulated the existence of other families of stars beyond our own. Unfortunately, their postulations — although correct — were not based in empirical data, and so could not be proven. This began to change during the 1920s and 30s, as astronomer Edwin Hubble set his sights on other galaxies, using the 2.5-meter (100-inch) telescope recently constructed on Mount Wilson in southern California. For the first time, Hubble was able to clearly see individual stars within M31 — the Andromeda… This story continues at The Next Web

One look at the image below, and at a glance, it might appear to be something a digital artist created. It’s an actual image of the Milky Way, the galaxy we live in, created by a Finnish astrophotographer named J-P Metsavainio. The single image of the Milky Way is 1.7 gigapixels and what you see below is only a portion … Continue reading

NASA has announced that astronomers have discovered evidence of an extremely long jet of particles emanating from a supermassive black hole in the early universe. The discovery was made using the Chandra X-Ray Observatory. If the finding is confirmed, it will mark the most distant supermassive black hole with a jet ever detected using x-rays. The supermassive black hole lies … Continue reading

Researchers at the University of Arizona are working on massive mirrors that will make it easier for telescopes to peer deep into space. The mirror being worked on by the University will be used in the Giant Magellan Telescope (GMT) that’s under construction in Chile. Despite being a terrestrial telescope, thanks in part to the new mirrors, the GMT will … Continue reading

One of the most studied objects in the sky is a supernova that first became visible with the naked eye in our sky on February 24, 1987. It was the first supernova visible with the naked eye in 400 years and was dubbed Supernova 1987A. Since its discovery, researchers have been looking for the squashed stellar core that would’ve been … Continue reading

The search for extraterrestrial life may not take us very far from home. Astronomers from the University of Copenhagen recently published an incredible study demonstrating there’s a high likelihood the Milky Way is absolutely flooded with potentially life-bearing planets. Published in Science Advances, the team’s paper entitled “A pebble accretion model for the formation of the terrestrial planets in the Solar System,” lays out and attempts to validate a theory that planets are formed by tiny, millimeter-sized pebbles massing together over time. According to the researchers: We show that a pebble accretion scenario for terrestrial planet formation provides explanations for… This story continues at The Next Web

The remains of a rare supernova have been discovered in our galaxy for the first time, raising new questions about the spread of key elements close to the center of the Milky Way. Though dramatic, supernovae aren’t necessarily uncommon, as stars tech their final evolutionary stages and go into runaway nuclear fusion. However, not all supernovae are created equal. Typically … Continue reading
That primordial mild that lingers whispers to us some very haunting long-lost techniques about an extremely historical period that endured long before there have been observers to experience it.It began their long trip to people 13.8 million decades ago--billions of years before our Solar System had shaped, and actually before our barred control Milky Way Universe had shaped, rotating just like a starlit pin-wheel in Space.The CMB involves people from Yös Kursu the faded time when all that endured was a turbulent beach of fiery, impressive radiation and a wild, rushing, screaming flood of primary particles.The old World wasn't the comparatively cold and quiet position it is now, and the more or less common people of the Universe--stars, planets, moons, and galaxies--all ultimately shaped using this newborn ton of primary contaminants, whilst the Galaxy significantly expanded and became significantly cooler and colder.We today search upon the Universe's desperate glow--the lingering ashes of its strange fiery formation--as it rushes ever quicker and faster to their not known fate.The CMB can be an almost-uniform history of radio dunes that floods the whole Cosmos.That gasoline was nearly entirely standard, however it did get some exquisitely tiny deviations using this ancient uniformity--strange spots which were just very slightly (1 portion in 100,000) pretty much heavy than their surroundings.These tiny deviations from total uniformity give astrophysicists with something special of sorts--a place of the primordial Universe--the CMB radiation.This valuable, beaming afterglow of our Universe's vanished babyhood provides the residual fossil imprints remaining as a legacy of those ancient particles--the structure of really, really small primordial strength modifications from which scientific cosmologists can decide to try to ascertain the attributes of the Universe.When the CMB radiation first embarked on its unbelievable journey billions of years back, it had been as beautiful and amazing as the top of a dazzling star--and it had been in the same way seething-hot.
About 280 light-years from Earth, a world of molten magma orbits one of the oldest stars in the galaxy. This exoplanet, 50% larger than the Earth, whips around its star at a breathtaking clip. Racing in tight circles 100 times closer to its star than the Earth maintains from the Sun, TOI-561 b burns with scorching surface temperatures over 2,000 Celsius (3,630 F). This is roughly twice as hot as molten lava on Earth, and is even hotter than magma studied inside laboratories. This proximity to TOI-561 further results in an ultra-short-period orbit, circling its 10-billion-year-old stellar parent once every 12 hours. “For every… This story continues at The Next Web
Facebook today revealed fresh details on how algorithms power your News Feed. In a blog post, Facebook said the ranking system isn’t comprised of a single algorithm. Instead, it uses multiple layers of machine learning models to predict what a user wants to see. Facebook explained how this would work for a fictional user called Juan: Since Juan’s login yesterday, his friend Wei posted a photo of his cocker spaniel. Another friend, Saanvi, posted a video from her morning run. His favorite Page published an interesting article about the best way to view the Milky Way at night, while his favorite cooking Group posted… This story continues at The Next WebOr just read more coverage about: Facebook
Galaxy collisions may both activate and power down black-hole powered galaxies.
Three-dimensional computer simulations have solved the mystery of why doomed stars explode at all.
At the center of the Milky Way lies the biggest object we can be sure exists: a supermassive black hole (SMBH) four million times more massive than the sun. Physicists believe these huge singularities can reach even greater sizes if they’ve eaten a big enough galaxy. The biggest estimates are somewhere in the range of 10 billion times more massive than our sun, but things begin to top out shortly after that. At least, that’s the conventional wisdom. A new study from a trio of European researchers recently unveiled a grander theory involving the formation of black holes. They say, under… This story continues at The Next Web
The opening years of the Fourth Century saw work begin on St. Peter’s Basilica in Rome, and the astronomer Pappus of Alexandria wrote details of his observation of an eclipse of the Sun. In the southern hemisphere, a star was seen erupting within a small, fuzzy patch of the night sky. Unfortunately, no records survived telling of this celestial event south of the equator. However, astronomers have now turned the mighty gaze of the Hubble Space Telescope to examine the remnants of this titanic explosion, called 1E 0102.2–729. By studying the cloud of gas and dust left behind, astronomers hope to piece… This story continues at The Next Web
