Earth"s Wobble Wreaks Havoc on Astronomers--And Astrologers, Too
Our planet’s precession is scarcely noticeable during anyone’s lifetime, but across history, it has had enormous effects.....»»
Scientists may have found signs of dark matter in Mars’s orbit
A wobble in Mars’ orbit could very well be a sign of dark matter, a new study posits. The study builds off the idea that … The post Scientists may have found signs of dark matter in Mars’s orbit appeared first on BGR. A wobbl.....»»

X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
Algorithm used on Mars rover helps scientists on Earth see data in a new way
A new algorithm tested on NASA's Perseverance Rover on Mars may lead to better forecasting of hurricanes, wildfires, and other extreme weather events that impact millions globally......»»
Plants could still grow well under alien skies
Photosynthesis changed Earth in powerful ways. When photosynthetic organisms appeared, it led to the Great Oxygenation Event. That allowed multicellular life to evolve and resulted in the ozone layer. Life could venture onto land, protected from the.....»»
Life might thrive on the surface of Earth for an extra billion years
The sun is midway through its life of fusion. It's about 5 billion years old, and though its life is far from over, it will undergo some pronounced changes as it ages. Over the next billion years, the sun will continue to brighten......»»
Hubble lights the way with new multiwavelength view of galaxy NGC 1559
The magnificent galaxy featured in this NASA/ESA Hubble Space Telescope image is NGC 1559. It is a barred spiral galaxy located in the constellation Reticulum, approximately 35 million light-years from Earth. The brilliant light captured in the curre.....»»

Scientists scan TRAPPIST-1 for technosignatures
If you are going to look for intelligent life beyond Earth, there are few better candidates than the TRAPPIST-1 star system. It isn't a perfect choice. Red dwarf stars like TRAPPIST-1 are notorious for emitting flares and hard X-rays in their youth,.....»»
Arctic weather satellite"s first images capture Storm Boris
Just a month after its launch, ESA's Arctic Weather Satellite has already delivered its first images, notably capturing Storm Boris, which has been wreaking havoc across central Europe......»»
NASA"s Chandra finds galaxy cluster that crosses the streams
Astronomers using NASA's Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure......»»
Don"t overlook microorganisms" role in planet health, scientists warn
The tiniest and oldest creatures on—and in—Earth have a huge role in achieving a sustainable future for the planet, an international team of scientists, including faculty researchers from The Ohio State University, asserts in a new Cell article p.....»»
Astronomers just detected the biggest black hole jets ever seen—and named them Porphyrion
The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy, the Milky Way......»»
Observers detect intraday variability of blazar 1ES 1426+42.8
Astronomers report the detection of optical intraday variability of a blazar known as 1ES 1426+42.8. The new findings, presented in a paper published in the September issue of Monthly Notices of the Royal Astronomical Society, could shed more light o.....»»
Visible-light-antenna ligand enhances samarium-catalyzed reactions
Samarium (Sm), a rare earth metal, is important to organic chemists because of the ability of its divalent compounds to efficiently perform single-electron transfer reductions......»»
NASA watches a peanut-shaped asteroid drift past Earth
Peanuts! Get your peanuts here! The solar system has been passing out peanuts lately in the form of two different oddly shaped asteroids that recently passed by Earth, and both look like over-sized peanuts......»»
Explaining dramatic planetwide changes after world"s last "Snowball Earth" event
Some of the most dramatic climatic events in our planet's history are "Snowball Earth" events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles (1 kilometer) thick......»»
Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary
Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September 10 on the preprint s.....»»
Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the atmospheres of exoplanets,.....»»
New research re-envisions Earth"s mantle as a relatively uniform reservoir
Lavas from hotspots—whether erupting in Hawaii, Samoa or Iceland—likely originate from a worldwide, uniform reservoir in Earth's mantle, according to an evaluation of volcanic hotspots published in Nature Geoscience......»»
