Geologists Have Found the Earth’s Missing Tectonic Plate Northern Canada has been keeping a secret from the rest of the world. It’s home to “Resurrection,” a tectonic plate that has been much theorized but never found until now. A team of researchers used what amounts to a CAT scan of northern Canada and the mantle underneath it to find the missing plate. Finding … Continue reading “Geologists Have Found the Earth’s Missing Tectonic Plate” The post Geologists Have Found the Earth’s Missing Tectonic Plate appeared first on Universe Today.

Astronomers Find the Hollowed-Out Shell of a Dwarf Galaxy that Collided With the Milky Way Billions of Years Ago In 2005 astronomers found a dense grouping of stars in the Virgo constellation. It looked like a star cluster, except further surveys showed that some of the stars are moving towards us, and some are moving away. That finding was unexpected and suggested the Stream was no simple star cluster. A 2019 study showed that … Continue reading “Astronomers Find the Hollowed-Out Shell of a Dwarf Galaxy that Collided With the Milky Way Billions of Years Ago” The post Astronomers Find the Hollowed-Out Shell of aRead More →

New study details atmosphere on ‘hot Neptune’ 260 light years away that ‘shouldn’t exist’ A team led by an astronomer from the University of Kansas has crunched data from NASA’s TESS and Spitzer space telescopes to portray for the first time the atmosphere of a highly unusual kind of exoplanet dubbed a “hot Neptune.” phys.org Go to SourceRead More →

Astronomers Challenge Recent Findings About Venus. “No Statistically Significant Detection of Phosphine” In September, a team of scientists reported finding phosphine in the upper atmosphere of Venus. Phosphine can be a biomarker and is here on Earth. But it’s also present on Jupiter, where it’s produced abiotically. The discovery led to conjecture about what kind of life might survive in Venus’ atmosphere, continually producing the easily-degraded phosphine. … Continue reading “Astronomers Challenge Recent Findings About Venus. “No Statistically Significant Detection of Phosphine”” The post Astronomers Challenge Recent Findings About Venus. “No Statistically Significant Detection of Phosphine” appeared first on Universe Today.

Scientists Think They Know What Caused the Deadliest Mass Extinction in the History of the Earth Humanity can have a love/hate relationship with itself, but there’s no denying that we’re the pinnacle of evolution on Earth as things stand now. But it took an awfully long time for evolution to produce beings such as we. Several times, life had to drag itself back from near annihilation. The largest extinction setback was … Continue reading “Scientists Think They Know What Caused the Deadliest Mass Extinction in the History of the Earth” The post Scientists Think They Know What Caused the Deadliest Mass Extinction in the HistoryRead More →

Weekly Space Hangout: October 21, 2020, Dr. Jill Tarter and the Search for Technosignatures This week we are excited (and honored) to welcome Dr. Jill Tarter to the Weekly Space Hangout. Best known for her work in the field of SETI, tonight Jill will be discussing the search for technosignatures. Dr. Jill Tarter is the Emeritus Chair for SETI Research at the SETI Institute in Mountain View, California and … Continue reading “Weekly Space Hangout: October 21, 2020, Dr. Jill Tarter and the Search for Technosignatures” The post Weekly Space Hangout: October 21, 2020, Dr. Jill Tarter and the Search for Technosignatures appeared first onRead More →

The implications of signs of life on Venus? The planet Venus has arguably remained less captivating than, say, the legendary tennis star or, for that matter, the women’s razor blade company—both of those Venuses have at least enjoyed ample airtime on cable TV. phys.org Go to SourceRead More →

What Would a Realistic Space Battle Look Like? Science fiction space movies can do a poor job of educating people about space. In the movies, hot-shot pilots direct their dueling space ships through space as if they’re flying through an atmosphere. They bank and turn and perform loops and rolls, maybe throw in a quick Immelman, as if they’re subject to Earth’s gravity. … Continue reading “What Would a Realistic Space Battle Look Like?” The post What Would a Realistic Space Battle Look Like? appeared first on Universe Today.

Improved model shows gamma rays and gold at merging neutron stars An international team of astrophysicists under Dutch leadership has demonstrated with an improved model that colliding neutron stars can emit gamma rays. Old models did not predict this and faltered since the merging of two neutron stars in 2017 that released gamma rays. The researchers publish their findings in the The Astrophysical Journal. phys.org Go to SourceRead More →

Smile, wave: Some exoplanets may be able to see us, too Three decades after Cornell astronomer Carl Sagan suggested that Voyager 1 snap Earth’s picture from billions of miles away—resulting in the iconic Pale Blue Dot photograph—two astronomers now offer another unique cosmic perspective: phys.org Go to SourceRead More →

NGC 1624-2 has a complex magnetospheric structure, observations reveal Using the Hubble Space Telescope (HST) and Canada-France-Hawaii Telescope (CFHT), astronomers have investigated a magnetized O-type star known as NGC 1624-2. Results of the study, presented in a paper published October 15 on the arXiv pre-print server, indicate that the star has a complex magnetospheric structure, what could have implications for our understanding of origin and evolution of magnetic fields in massive stars. phys.org Go to SourceRead More →

Success! OSIRIS-REx Touches Asteroid Bennu to Collect Samples Out in the asteroid belt, 207 million miles (334 million km) from Earth, a little spacecraft briefly touched down on the surface of Asteroid Bennu today, attempting to collect samples of dust and rocks. NASA’s OSIRIS-REx spacecraft (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) spent about 10 seconds on the ancient asteroid to collect … Continue reading “Success!
