CHESS mission will check out the space between stars

Fri, 23 Jun 2017 13:20:29 EDT

Deep in space between distant stars, space is not empty. Instead, there drifts vast clouds of neutral atoms and molecules, as well as charged plasma particles called the interstellar medium—that may, over millions of years, evolve into new stars and even planets. These floating interstellar reservoirs are the focus of the NASA-funded CHESS sounding rocket mission, which will check out the earliest stages of star formation.

Scientists uncover origins of the Sun's swirling spicules

Thu, 22 Jun 2017 16:01:07 EDT

At any given moment, as many as 10 million wild jets of solar material burst from the sun's surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and despite their grass-like abundance, scientists didn't understand how they form. Now, for the first time, a computer simulation—so detailed it took a full year to run—shows how spicules form, helping scientists understand how spicules can break free of the sun's surface and surge upward so quickly.

Magnetic memories of a metal world

Thu, 22 Jun 2017 10:22:38 EDT

4.5 billion years ago in the violent, high-speed environment of the early solar system, a protoplanet roughly the size of Mars was involved in a series of fierce collisions with other large planetary bodies.



Space tourism could boost science and health research—here's how

Thu, 22 Jun 2017 09:30:01 EDT

The announcement of the draft Spaceflight Bill in the Queen's Speech will allow the development of spaceports in the UK. This could see members of the paying public launched into space as tourists, or taking sub-orbital flights from London to New York in just 45 minutes.



Could asteroids bombard the Earth to cause a mass extinction in 10 million years?

Thu, 22 Jun 2017 09:20:17 EDT

Scientists have spent decades debating whether asteroids and comets hit the Earth at regular intervals. At the same time, a few studies have found evidence that the large extinction events on Earth – such as the one that wiped out the dinosaurs 66m years ago – repeat themselves every 26m to 30m years. Given that there's good evidence that an asteroid triggered the dinosaur extinction, it makes sense to ask whether showers of asteroids could be to blame for regular extinction events.



Unseen 'planetary mass object' signalled by warped Kuiper Belt

Thu, 22 Jun 2017 08:51:44 EDT

An unknown, unseen "planetary mass object" may lurk in the outer reaches of our solar system, according to new research on the orbits of minor planets to be published in the Astronomical Journal. This object would be different from—and much closer than—the so-called Planet Nine, a planet whose existence yet awaits confirmation.



JPL scientists predict future space probes will have artificial intelligence to operate autonomously

Thu, 22 Jun 2017 08:50:03 EDT

Radioactive elements in Cassiopeia A suggest a neutrino-driven explosion

Wed, 21 Jun 2017 09:40:21 EDT

Stars exploding as supernovae are the main sources of heavy chemical elements in the Universe. In particular, radioactive atomic nuclei are synthesized in the hot, innermost regions during the explosion and can thus serve as probes of the unobservable physical processes that initiate the blast. Using elaborate computer simulations, a team of researchers from the Max Planck Institute for Astrophysics (MPA) and RIKEN in Japan were able to explain the recently measured spatial distributions of radioactive titanium and nickel in Cassiopeia A, a roughly 340 year old gaseous remnant of a nearby supernova. The computer models yield strong support for the theoretical idea that such stellar death events can be initiated and powered by neutrinos escaping from the neutron star left behind at the origin of the explosion.
