First direct seismic measurements of mars reveal a geologically active planet

The first reports of seismic activity and ground vibrations on Mars show the red planet has a moderate level of seismic activity, intermediate between Earth and the Moon, with a few quakes that contain distinct wave patterns similar to quakes on Earth caused by the movement of tectonic plates.

Solar storms could scramble whales' navigational sense

When our sun belches out a hot stream of charged particles in Earth's general direction, it doesn't just mess up communications satellites. It might also be scrambling the navigational sense of California gray whales (Eschrichtius robustus), causing them to strand on land, according to a Duke University graduate student. Gray whales were 4.3 times more likely to strand when a lot of radio frequency noise from a solar outburst was hitting the Earth.

Betelgeuse mystery solved? New deep-space image stirs up fresh theories behind dimming star

One of the biggest and brightest stars in the night sky has left astronomers puzzled after it has faded dramatically over the last year. Some have speculated that this is a sign of an impending supernova explosion, but new observations are pointing toward two new theories.Betelgeuse is a red supergiant star located around 700 light years away from Earth that can be found glowing orange in the well-known constellation of Orion. It is so massive that if it were placed in the center of our solar sy...

Massive planet that would dwarf Jupiter has been discovered in our galactic neighborhood

Just 330 light-years from Earth, a massive baby planet named 2MASS 1155–7919 b has recently been born from a cloud of gas and dust. Researchers from the Rochester Institute of Technology (RIT) found this rare young gas giant, 10 times larger than Jupiter, orbiting far from its stellar companion— 600 times further from its parent star than the Earth is from the Sun. The star around which this planet orbits is also extremely young, having formed just five million years ago, roughly one-thousandth ...

DNA from ancient packrat nests helps unpack Earth's past

New work shows how using next-generation DNA sequencing on ancient packrat middens--nests made out of plant material, fragments of insects, bones, fecal matter, and urine--could provide ecological snapshots of Earth's past. Published today in the journal Ecology and Evolution, the study may pave the way for scientists to better understand how plant communities--and possibly animals, bacteria, and fungi as well--will respond to human-caused climate change.

MIT system predicts the best way to deflect an Earth-bound asteroid

We’re not in immediate danger of any asteroids colliding with Earth – at least not as far as anyone’s aware. But it’s not like it hasn’t happened before, and there is an expected near-miss coming up in 2029. Accordingly, it’s probably best to be prepared, and MIT researchers have developed a system that could help determine the best possible method to avoid a collision – long before the situation becomes desperate. An MIT team led by former MIT graduate student Sung Wook Paek describe a ‘decisio...

German Man Finds Rock From Early Solar System in His Front Yard

Scientists have released their initial analysis of a meteorite that fell over Europe last September. They report that the rock, the remnant of a daytime bolide that impacted Earth with an energy of 0.48 kilotons of TNT (around this much), is a carbonaceous chondrite—the kind of meteor that contains material from the…Read more...

Research: Early humans in Africa may have interbred with an unknown species

One of the more startling discoveries arising from genomic sequencing of ancient hominin DNA is the realization that all humans outside Africa have traces of DNA in their genomes that do not belong to our own species. The approximately six billion people on Earth whose recent ancestry is not from Africa will have inherited between 1% and 2% of their genome from our closest but now extinct relatives: the Neanderthals. East Asians and Oceanians have also inherited a small amount of ancestry from t...

Inside the High Stakes Missions of NASA’s Oldest Deep-Space Probes

On Aug. 20, 1977, NASA launched the Voyager 2 probe on a mission to explore the outer planets of our solar system.Twelve years later, having scanned Jupiter, Saturn, Uranus and Neptune, the 1,600-pound spacecraft completed its initial mission.But it kept going. And going. And going. Nursed farther and farther into space by a small team at NASA’s Jet Propulsion Laboratory in California, Voyager 2 is now more than 11 billion miles from Earth, making it the second-most-distant man-made object from ...

Do the climate effects of air pollution impact the global economy?

Aerosol emissions from burning coal and wood are dangerous to human health, but it turns out that by cooling the Earth they also diminish global economic inequality, according to a new study by Carnegie's Yixuan Zheng, Geeta Persad, and Ken Caldeira, along with UC Irvine's Steven Davis.

Set your alarm: Moon, Mars and Earth to align before dawn on Tuesday

An eclipse-like event will cause Mars to vanish from the sky over North America early Tuesday morning in a rare event known to astronomers as a lunar occultation.Similar to an eclipse when the Earth, moon and sun fall in line, during an occultation, the Earth, moon and a planet align. As a result, the Red Planet will be hidden from sight as it appears to pass directly behind the moon during Tuesday's event. The planet Venus is visible on top of the moon as viewed from Quezon City, north o...

Carl Sagan's Pale Blue Dot image is 30 years old today

Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes' cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was not to be missed. From my liner notes to the Voyager Golden Record vinyl box set: Astronomer and educator Carl Sagan, a member of the Voyager Imaging Team,...

Coincidences influence the onset and ending of ice ages

An analysis of the so called climate spectrum shows why the ice ages have not behaved precisely as the models predict. A large element of coincidence is involved when an ice age begins or ends, the analysis shows. Peter Ditlevsen from Physic of Ice, Climate and Earth at the Niels Bohr Institute, University of Copenhagen says the results imply we should maybe use a more conservative risk assessment then the one IPCC recommends. The result is now published in Climate Dynamics.

Shutting down flat Earthers, Neil deGrasse Tyson style

What is the point of debate when one side the argument is objectively true? There is none. That is, unless the incorrect arguer has the ability to influence the masses. When a relatively famous musician began spewing flat Earth views on social media, astrophysicist Neil deGrasse Tyson knew he had to jump in the ring and defend science with science. General belief systems aren't a threat, but it's important to combat incorrect and dangerous views when they have a chance of pervading greater socie...
