What’s Causing the Mysterious Radio Waves Coming From the Center of the Milky Way?

The center of the Milky Way is a mysterious place. Astronomers think there’s a supermassive black hole there, though it could be dark matter instead. The region is densely packed with stars, dominated by red giants. And because of all the dust between Earth and the galactic center, we can’t see anything with visible light, ultraviolet light, or low-energy x-rays.

But we can detect radio waves, and there are some unexplained ones coming from the center of the galaxy, and adding to the mystery.

Europa has Water in its Atmosphere

Since the Voyager probes passed through the Jupiter system in 1979, scientists have been intrigued and mystified by its moon Europa. Once the images these probes acquired of the moon’s icy surface returned to Earth, scientists began to speculate about the possibility of a subsurface ocean. Since then, the detection of plume activity and other lines of evidence have bolstered this theory and fed speculation that there could be life beneath Europa’s icy surface.

According to new research, another critical piece of evidence of Europa’s watery nature has at least been confirmed. Using a similar technique that confirmed the presence of atmospheric water vapor in Jupiter’s moon Ganymede, Lorenz Roth of the KTH Royal Institute of Technology confirmed that Europa has water vapor in its atmosphere. This discovery could lead to a greater understanding of Europa’s atmosphere and surface environment, informing missions headed there in the near future.

A Magnetic Tunnel Surrounds the Earth

What if our eyes could see radio waves?

If we could, we might be able to look up into the sky and see a tunnel of rope-like filaments made of radio waves. The structure would be about 1,000 light-years long and would be about 350 light-years away.

This tunnel explains two of the brightest radio features in the sky.

Volcanism on the Moon Ended About 2 Billion Years ago

According to the most widely accepted theories, the Moon formed about 4.5 billion years ago after a Mars-sized object (Theia) collided with Earth. After the resulting debris accreted to create the Earth-Moon system, the Moon spent many eons cooling down. This meant that a few billion years ago, lakes of lava were flowing across the surface of the Moon, which eventually hardened to form the vast dark patches (lunar maria) that are still there today.

Thanks to the samples of lunar rock brought back to Earth by China’s Mens Executive Cufflinks Enamel Two Player Tic Tac Toe Winning G mission, scientists are learning more about how the Moon formed and evolved. According to a recent study led by the Chinese Academy of Geological Sciences (CGAS), an international team examined these samples to investigate when volcanism on the Moon ended. Their results are not only filling in the gaps of the Moon’s geological history but also of other bodies in the Solar System.

Why do Uranus and Neptune Have Magnetic Fields? Hot ice

The outer “ice giant” planets, Neptune and Uranus, have plenty of mysteries.  One of the biggest is where exactly they got their Christmas Nail Art Foil Transfer Stickers Winter Nail Art Suppli.  They are strong at that, with Neptune’s being twenty-seven times more powerful than Earth’s, while Uranus’ varies between ?  and four times Earth’s strength.  Chaos rules in these electromagnetic environments, making them exceptionally hard to both understand and model.  Now a team of researchers led by Dr. Vitali Prakpenka of the University of Chicago thinks they might have found the underlying cause of both the field’s strength and its randomness – “hot ice.”

This’ll be us… in 5 Billion Years

Scientists have long known the fate of our solar system – and likely the fate of Earth itself.   In a few billion years, the Sun will run out of fusion fuel and expand to a “red giant” phase, likely swallowing everything in the solar system up to the orbit of Mars.  But, some of the planets past that point could survive, like Jupiter and Saturn.  Now, scientists have used the Keck Observatory to see a system that looks like what ours will after the Sun’s red giant phase for the very first time.

The idea of avoiding asteroid impacts has featured prominently in the public’s mind for decades – especially since the release of Deep Impact and Armageddon.  But is using a nuclear explosion the best way to deal with potentially hazardous space rocks?  Decidedly not.  If given enough time, there is a much more effective (and safer) way to dealing with any object on a collision course with Earth – a gravity tractor.  Now, Dr. Yohannes Ketema from the University of Minnesota has developed a flight pattern that makes this simplest of all asteroid defense mechanisms that much more effective.

Did Titan Give Saturn its Tilt?

Giant planets like Saturn don’t just tilt over all by themselves: something has to knock them over, or tug on them gravitationally, to push them off axis. Scientists expect that when new planets are born, they form with almost no tilt at all, lining up like spinning tops, with their equators level to the orbital plane in which they circle around their sun.

But no planet in our solar system is perfectly level. Jupiter is the closest, boasting an obliquity (tilt) of just 3.12 degrees. Earth’s obliquity is much more substantive at 23.45 degrees, causing us to experience an annual cycle of seasons as our homeworld wobbles on its axis. Saturn’s tilt is more extreme yet, with an obliquity of 26.73 degrees (though it’s nowhere near as extreme as Uranus, which is practically sideways, spinning at a 97.86-degree angle to its orbital plane).

We can learn a lot from these obliquities.

William Shatner Completes his Trip to Space With Blue Origin

After traveling to the edge of space this week, William Shatner and the crew of the NS-18 mission made it back to Earth safe and sound. This was the second time Blue Origin’s New Shepard launch vehicle flew to space with a crew aboard, and as with the inaugural flight, Blue Origin founder Jeff Bezos decided to enlist some star power! Who better than the man known to millions of fans as James Tiberius Kirk, Captain of the starship Enterprise?

At 90 years of age, the veteran actor of television, film, and stage is the oldest person to fly to space. The previous record was held by 82-year old veteran aviator Wally Funk, who went to space as part of the first crewed flight of the New Shepard on July 20th. Along with his fellow crewmembers, Shatner’s experienced what it’s like to go to space for the first time from the company’s Launch Site One facility in West Texas.
