“Our results could give us a new perspective on the evolution of the Earth’s dynamics,” said Motohiko Murakami, a corresponding author of the study explained in a press statement. “They suggest that Earth, like the other rocky planets Mercury and Mars, is cooling and becoming inactive much faster than expected.”

The Earth will cool down at an increasingly fast pace

The scientists discovered that bridgmanite was roughly 1.5 times better at conducting heat than previously estimated. This means that heat must transfer more easily from the core to the mantle than had been previously believed. This faster transfer equals a higher cooling rate, meaning the Earth’s core will cool down faster than once thought. What’s more, as it cools bridgmanite turns into a mineral called post-perovskite, which conducts heat at an even faster rate. So the inner Earth could start to cool at an increasingly accelerated rate once bridgmanite starts forming into post-perovskite, a crystal structure following the formula ABX₃.

Its aim is to help us understand the past and future of the universe.

You may have heard of the Dark Energy Spectroscopic Instrument (DESI) from the Lawrence Berkeley National Laboratory’s Department of Energy. We reported on the project all the way back in 2016 when the team of scientists launched 5,000 small robots into space to help develop the first map of the universe beyond earth.

Then, in 2017, we reported how the project had created a 3D map of our galaxy’s space dust. The map was successful at plotting each individual dust that exists in our galaxy in order to clear up the deep space view and measure the accelerating expansion rate of the universe.

There a spacecraft so far away in space it has become the first humanmade object to reach interstellar space. It is traveling out there among the stars, far from Earth, far from home. Voyager 1 is set to never return to our star system, let alone Earth. Its mission; to explore the most distant reaches of space.

September 5, 2020, marked 43 since NASA’s Voyager 1 spacecraft launched from Cape Canaveral. In 2012, the probe became the first object to enter an uncharted, never-before-seen region of space; interstellar space. More precisely, on August 25, 2012, at 122 astronomical units, the probe left the so-called heliopause, and so became the first to reach interstellar space.

NASA had a big 2021 and finally launched the James Webb Telescope. But its 2022 schedule is nothing to sneeze at.

“Don’t look up” — where Earth is threatened by a “planet killer” asteroid.

We now know of almost 5,000 planets outside the Solar System. If you were to picture what it would be like on one of these distant worlds, or exoplanets, your mental image would probably include a parent star—or more than one, especially if you’re a Star Wars fan.

But scientists have recently discovered that more planets than we thought are floating through space all by themselves—unlit by a friendly stellar companion. These are icy “free-floating planets,” or FFPs. But how did they end up all on their own and what can they tell us about how such planets form?

Finding more and more exoplanets to study has, as we might have expected, widened our understanding of what a planet is. In particular, the line between planets and “brown dwarfs”— cool stars that can’t fuse hydrogen like other stars —has become increasingly blurred. What dictates whether an object is a planet or a brown dwarf has long been the subject of debate—is it a question of mass? Do objects cease to be planets if they are undergoing nuclear fusion? Or is the way in which the object was formed most important?

“This is really an origin story; for the first time we can explain how all nearby star formation began,” says astronomer and data visualization expert Catherine Zucker who completed the work during a fellowship at the CfA.

The paper’s central figure, a 3D spacetime animation, reveals that all young stars and star-forming regions — within 500 light years of Earth — sit on the surface of a giant bubble known as the Local Bubble. While astronomers have known of its existence for decades, scientists can now see and understand the Local Bubble’s beginnings and its impact on the gas around it.

India is one of only a handful of nations that have sent probes to the moon and Mars. But the most impressive part of its space program is its cost-effectiveness. Unlike other government space organizations, India’s agency is extremely efficient, with the lowest cost-per-kilogram in the industry. Now India is throwing open its doors to private companies and raising its stellar ambitions.
