30 Years Ago, Astronomers Discovered The First Exoplanet — And It’s Still Totally Bizarre

It got weird, fast.

And what about Wolszczan’s pulsar detection method? As precise as it is, shouldn’t it have revealed many such pulsar planets by now?

That’s the thing, according to Wolszczan. “I’ve been engaged with a number of long-term surveys, which were to search for millisecond pulsars and then look for planets around them,” he says, and while they’ve found a few objects around neutrons stars, they’ve found nothing like the PSR B1257+12 system. “That is the disappointing part of the whole story.”

It remains a mystery why the first confirmed exoplanet appears to be part of a one-of-a-kind system. But then, exoplanet science is still relatively young and full of surprises. Star systems once assumed to be entirely hostile to life may yet prove to provide it a narrow niche.

Deep Space Food Challenge: NASA Offers $1 Million for Innovative Systems to Feed Tomorrow’s Astronauts

As NASA prepares to send astronauts further into the cosmos than ever before, the agency aims to upgrade production of a critical fuel source: food. Giving future explorers the technology to produce nutritious, tasty, and satisfying meals on long-duration space missions will give them the energy required to uncover the great unknown.

Unusual Team Finds Gigantic Planet Hidden in Plain Sight — Much Closer to Earth Than Others Like It

A UC Riverside astronomer and a group of eagle-eyed citizen scientists have discovered a giant gas planet hidden from view by typical stargazing tools.

The planet, TOI-2180 b, has the same diameter as Jupiter.

Jupiter is the largest planet in the solar system and the fifth planet from the sun. It is a gas giant with a mass greater then all of the other planets combined. Its name comes from the Roman god Jupiter.

This is what big companies want from car and truck makers in EVs

Vehicle manufacturers are ramping up electric vehicle production, so big companies like Amazon, AT&T, and IKEA are telling vehicle manufacturers what kinds of EVs they want. Here’s the “blueprint” that members of the Corporate Electric Vehicle Alliance are today presenting to makers like Volvo, GM, and Daimler explaining which EVs they want to purchase in the United States over the next five years.

In January 2020, as Electrek then reported, Boston-based sustainability nonprofit group Ceres launched the Corporate Electric Vehicle Alliance, a group to help companies accelerate the transition to electric vehicles.

Five of the most exciting telescope pictures of the universe

Some of these objects are among the oldest and most distant known. Here we’re seeing light from ancient stars whose local contemporaries have long since been extinguished.

The oldest galaxies formed during the epoch of reionisation, when the tenuous gas in the universe first became bathed in starlight which was capable of separating electrons from hydrogen. This was the last major change in properties of the universe as a whole.

The fact that light carries so much information, allowing us to piece together the history of the universe, is remarkable. The launch of the James Webb Space Telescope will give us some vastly improved infrared images, and will inevitably raise new questions to challenge future generations of scientists.

Cosmic Birefringence from Planck Data Release 4

We search for the signature of parity-violating physics in the cosmic microwave background, called cosmic birefringence, using the Planck data release 4. We initially find a birefringence angle of β=0.30±0.11 (68% C.L.) for nearly full-sky data. The values of β decrease as we enlarge the Galactic mask, which can be interpreted as the effect of polarized foreground emission. Two independent ways to model this effect are used to mitigate the systematic impact on β for differen… See more.
