A nearby system hosts the first Earth-sized planet discovered by NASA's Transiting Exoplanets Survey Satellite, as well as a warm sub-Neptune-sized world, according to a new paper from a team of astronomers that includes Carnegie's Johanna Teske, Paul Butler, Steve Shectman, Jeff Crane, and Sharon Wang.Their work is published in

Now We Know That Dark Matter Isn’t Primordial Black Holes
For over fifty years, scientists have theorized that roughly 85% of matter in the Universe’s is made up of a mysterious, invisible mass. Since then, multiple observation campaigns have indirectly witnessed the effects that this “Dark Matter” has on the Universe. Unfortunately, all attempts to detect it so far have
International team of physicists continues search for new physics
Dark matter, which is thought to account for nearly a quarter of matter in the universe (but has yet to be observed), has perplexed physicists for decades. They're constantly looking for something surprising to show up in experiments—results that deviate from the standard model that defines elementary physics.It's no wonder
Brightest quasar ever found shines with the intensity of 600 trillion Suns
From our point of view here on Earth, the brightest object in the sky is unquestionably the Sun. But this unremarkable star is a mere 10-watt bulb compared to quasars, extremely luminous galactic cores that shine so intensely thanks to their ravenous hunger for nearby material. Now, astronomers have detected
X-ray pulse detected near event horizon as black hole devours star
Caught in the Act—Astronomers Get Their Best Look Yet at a Supernova Blowing Up
Georgios Dimitriadis thought he had botched the data. It was late on a Friday night and the University of California, Santa Cruz, astronomer was the last one in the office. He had been waiting anxiously for NASA’s planet-hunting Kepler space telescope to stream a batch of data toward Earth—not because
Helium exoplanet inflated like a balloon, research shows
Astronomers have discovered a distant planet with an abundance of helium in its atmosphere, which has swollen to resemble an inflated balloon.An international team of researchers, including Jessica Spake and Dr David Sing from the University of Exeter, have detected the inert gas escaping from the atmosphere of the exoplanet
Physicists Keep Attempting– and Failing– to Discover Dark Matter in Dark Places
Researchers began viewing crystals shimmer in the 1990 s. Those crystals sparkled more in the summer season, which scientists took as proof of dark matter. However those researchers were most likely incorrect, brand-new research study recommends.Researchers have great factor to think that dark matter exists— that there’s some hidden
Scientists detect biggest known black-hole collision
An international team of scientists have detected ripples in space and time, known as gravitational waves, from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun – and from another three black-hole mergers.The Australian National University (ANU) is playing a lead
Alexa, Cortana, Siri? How to Choose a Smart Voice Assistant for Your Smart Home
Smart home devices are getting momentum. According to reports, over 39 million people in the United States alone own a smart voice assistant, also called smart speaker.Smart Speakers are easy to use and come with a well known in-home voice assistant such as Siri, Alexa, Google Assistant, or Cortana. Home smart
Astronomers have measured all the starlight ever emitted
Water Has Been Detected in The Atmosphere of a Planet 179 Light Years Away
Gathering detailed information on exoplanets is extremely difficult. The light from their host star overwhelms the light from the exoplanet, making it difficult for telescopes to see them.But now a team using cutting-edge technology at the Keck Observatory has taken a big leap in exoplanet observation and has detected water
