Destructive Super Solar Storms Hit Us Every 25 Years Or So

Solar storms powerful enough to wreak havoc on electronic equipment strike Earth every 25 years, according to a new study. And less powerful—yet still dangerous—storms occur every three years or so. This conclusion comes from a team of scientists from the the University of Warwick and the British Antarctic Survey.

These powerful storms can disrupt electronic equipment, including communication equipment, aviation equipment, power grids, and satellites.

The CHEOPS (CHaracterising ExOPlanets Satellite) spacecraft just opened the cover on its telescope. The spacecraft was launched on December 18th 2019 and has so far performed flawlessly. In one or two weeks we could get our first images from the instrument.

It Looks Like James Webb’s Launch Date is Going to Slip to July 2021

Put “James Webb Telescope launch” into your search engine and you’ll be flooded with links, some reaching back to the ‘scope’s first proposed launch date in 2010. The delayed launch of the space telescope is a running theme in the space community, even though we all know it’s going to be worth the wait. So nobody will be surprised by this latest development in the story of the world’s most anticipated telescope.

NASA is Going to Add a Commercial Module to the Space Station

NASA’s plan to open up the International Space Station (ISS) to commercial activity is gaining ground. They have a vision for an economy in Low-Earth Orbit (LEO) called the Plan for Commercial LEO Development. According to NASA, they intend to foster economic development in LEO and to drive innovation, all for the benefit of the American economy.

Now they’ve selected Axiom Space of Houston to provide a commercial habitation module for the ISS.

Okay, this Logo Proves that Space Force Should Have Really Been Called Star Fleet

Now that the US Space Force’s new uniforms have been eviscerated on social media (that was so last week) it’s up to their new logo to keep the uproar going. The newest branch of the US Armed Forces hasn’t disappointed: their logo looks like the Star Fleet logo from Star Trek, inviting all kinds of rancorous comparisons on the internet.

A Cubesat Deployed a De-Orbiting Tether and Now it’s Losing Altitude 24 Times Faster than Before

A company called Tethers Unlimited has deployed its de-orbiting tether in a successful test on the Prox-1 satellite. The satellite is one of four that are carrying the device, called the Terminator Tape. Rather than stay in space for years or decades, and add to the growing problem of space debris, Prox-1 is using its Terminator Tape to slowly lower its orbit.

The Brightest Supernova Ever Seen was Caused by a White Dwarf Spiraling into a Red Giant

Super-luminous supernovae are the brightest explosions in the Universe. In just a few months, a super-luminous supernova can release as much energy as our Sun will in its entire lifespan. And at its peak, it can be as bright as an entire galaxy.

One of the most-studied super-luminous supernovae (SLSN) is called SN 2006gy. Its origin is uncertain, but now Swedish and Japanese researchers say they might have figured out what caused it: a cataclysmic interaction between a white dwarf and its massive partner.

OSIRIS-REx Flew 620 Meters Above its Landing Site. Confirms that it’s a Boulder-Strewn Nightmare, Just Like the Rest of Bennu

NASA’s OSIRIS-REx spacecraft reached its target, asteroid Bennu (101955 Bennu), on December 3rd, 2018. Since then, the spacecraft has been examining the asteroid’s surface, looking for a suitable landing spot to collect a sample. The problem is, Bennu has a much rockier and challenging surface than initially thought.

This is Probably Sandstone Layers on Mars. Absolutely Beautiful

NASA’s Mars Reconnaissance Orbiter (MRO) has been in orbit around Mars for almost 14 years. It carries a variety of instruments with it, including the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument. That instrument has collected thousands of images of Mars.

Rosetta Saw the Building Blocks of Life on Comet 67P

Why is there so little nitrogen in Comet 67P/Churyumov-Gerasimenko (67P)? That’s a question scientists asked themselves when they looked at the data from the ESA’s Rosetta spacecraft. In fact, it’s a question they ask themselves every time they measure the gases in a comet’s coma. When Rosetta visited the comet in 2014, it measured the gases and found that there was very little nitrogen.

In two new papers published in Nature Astronomy, researchers suggest that the nitrogen isn’t really missing at all, it’s just hidden in the building blocks of life.
