The Perseid Meteor Shower Is Going to Be Amazing This Weekend

If you have camping plans this weekend, you’re in luck. The annual Perseid meteor shower will be returning August 10–13, and it’s expected to be the best and brightest one in years, astrophysicist Ethan Siegel writes for Forbes.

The Perseid meteor shower—named after the Perseus constellation, where the meteors originate—occurs every August when the Earth passes through a path of debris left by the Swift-Tuttle comet. This comet orbits the Sun once every 133 years, and in doing so, the intense heat and tidal forces cause parts of the comet to break off, creating a floating field of debris. The dust and particles left behind compose a comet's two tails: the ion tail and the dust tail.

According to Siegel, a few factors determine how spectacular a meteor shower will be, including light pollution conditions, how close Earth gets to the center of the debris stream, the relative speed of the debris to Earth, and the stream's density. Plus, the new moon phase on August 11 guarantees a darker sky. For this reason, Saturday night should be the best time to head outside and look up.

"The Moon is very favorable for the Perseids this year, and that'll make the Perseids probably the best shower of 2018 for people who want to go out and view it,” NASA meteor expert Bill Cooke tells Space.com.

You’ll probably be able to see 60 to 70 meteors per hour at its peak. The most important consideration is to head somewhere with dark skies and little light pollution. For guidance, you can check out this online map of artificial sky brightness. Once you arrive at your preferred viewing spot, wait for the sky to get completely dark—about 2 to 3 hours after sunset.

Swift-Tuttle, the same comet that gives us these dazzling meteor displays, might also collide with Earth and wipe out life as we know it—but not for another 2460 years, at the very least. So until then, sit back and enjoy the cosmic show.

What Is the Kitchen Like on the International Space Station?

Clayton C. Anderson:

The International Space Station (ISS) does not really have a "kitchen" as many of us here on Earth might relate to. But, there is an area called the "galley" which serves the purpose of allowing for food preparation and consumption. I believe the term "galley" comes from the military, and it was used specifically in the space shuttle program. I guess it carried over to the ISS.

The Russian segment had the ONLY galley when I flew in 2007. There was a table for three, and the galley consisted of a water system—allowing us to hydrate our food packages (as needed) with warm (tepid) or hot (extremely) water—and a food warmer. The food warmer designed by the Russians was strictly used for their cans of food (about the size of a can of cat food in America). The U.S. developed a second food warmer (shaped like a briefcase) that we could use to heat the more "flexibly packaged" foodstuffs (packets) sent from America.

Later in the ISS lifetime, a second galley area was provided in the U.S. segment. It is positioned in Node 1 (Unity) and a table is also available there for the astronauts' dining pleasures. Apparently, it was added because of the increasing crew size experienced these days (6), to have more options. During my brief visit to ISS in 2010 (12 days or so) as a Discovery crewmember, I found the mealtimes to be much more segregated than when I spent five months on board. The Russians ate in the Russian segment. The shuttle astronauts ate in the shuttle. The U.S. ISS astronauts ate in Node 1, but often at totally different times. While we did have a combined dinner in Node 1 during STS-131 (with the Expedition 23 crew), this is one of the perceived negatives of the "multiple-galley" scenario. My long duration stint on ISS was highlighted by the fact that Fyodor Yurchikhin, Oleg Kotov, and I had every single meal together. The fellowship we—or at least I—experienced during those meals is something I will never, ever forget. We laughed, we argued, we celebrated, we mourned …, all around our zero-gravity "dinner table." Awesome stuff!

The Northern Lights Could Be Visible Over Parts of the U.S. This Week

Residents in the northern U.S. could be treated to a rare meteorological spectacle this week. As USA Today reports, the northern lights will likely be visible over certain states from May 15 to May 17, including Maine, Michigan, and Montana.

An aurora borealis, an event caused by solar particles colliding with atoms in Earth's atmosphere, is normally limited to countries at higher latitudes like Iceland. On rare occasions, increased activity from the Sun results in stronger and more widespread auroras on our planet.

Following a significant release of plasma and magnetic energy from the Sun's corona, the Space Weather Prediction Center announced a geomagnetic storm watch for this week. The Coronal Mass Ejections (CMEs) are expected to reach Earth on Wednesday, May 15, and persist through Friday. During that time, the prediction center says the northern lights may appear over parts of the contiguous United States. Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Illinois, Michigan, New York, and most of New England all fall within the projected aurora zone.

The solar storm will peak at a G2 (moderate) level on May 16—which makes Thursday night and Friday morning the best times to catch the light show. As is the case with stars and meteor showers, people in major cities will have trouble seeing the event. Their best bet is to find a high vantage point with little light pollution.
