Swirling Clouds in Jupiter's Atmosphere Captured in Stunning New Photograph

Since launching from Earth in 2011 and entering Jupiter's orbit in 2016, the NASA space probe Juno has revealed astonishing facts about the gas giant. The mission has allowed scientists to see more of Jupiter's atmosphere than ever before, from the ammonia cyclones at its poles to the category-12 hurricane that makes up its red eye. One of the latest images from Juno shows what NASA has dubbed "dramatic atmospheric features" churning in the planet's northern hemisphere.

Juno snapped the photo above while performing its 18th close flyby of Jupiter on February 12, 2019. The image depicts the planet's clouds swirling around a jet stream region called Jet N6 as seen from 8000 miles above the clouds.

After pulling the raw image from JunoCam's database, a citizen scientist named Kevin M. Gill enhanced the colors and rotated the picture 100 degrees to the right. Like many photographs captured in space, the final image serves as scientific evidence as well as a piece of art.

The JunoCam has taken more than 100 photos of Jupiter's surface that are available online. Anyone can download the images from NASA's website and edit them to make some stellar art of their own.

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.

Mark Your Calendars: An Enormous Asteroid Will Fly Past Earth on April 13, 2029

An asteroid that’s roughly the size of three football fields is on track to whiz past Earth on April 13, 2029. Fortunately for us, it isn’t in danger of hitting our humble planet, according to Space.com.

The asteroid, which was discovered in 2004, is named Apophis after the Egyptian spirit of evil and destruction. Scientists previously suggested that there was a 2.7 percent chance of it striking Earth, but the odds were later reduced to “less than one in a million,” Don Yeomans, a retired planetary scientist for NASA, said in 2013.

Indeed, if it were ever to collide with Earth, “it would cause major damage to our planet and likely to our civilization as well,” according to a statement issued for the 2019 International Academy of Astronautics's Planetary Defense Conference [PDF].

On the bright side, the asteroid is expected to put on quite the show. Because it will come within 19,000 miles of Earth—which is pretty close by celestial standards—it will be visible to the naked eye. NASA says Apophis will soar over Australia before heading across the Indian Ocean, Africa, the Atlantic Ocean, and finally the United States. It will be visible in the eastern U.S. by mid-morning, but its closest approach will be just before 6 p.m. EDT. “By 7 p.m. EDT, the asteroid will have crossed over the United States,” NASA wrote in a statement.

Here’s what its path will look like:

Huge hunks of space rock hurtling toward Earth are not only great fodder for action-packed blockbuster films; they’re also a great way for scientists to learn more about these heavenly bodies. Although small asteroids measuring 5 to 10 meters across sometimes fly by Earth, it’s rare to get a close-up look at asteroids the size of Apophis.

“The Apophis close approach in 2029 will be an incredible opportunity for science,” Marina Brozović, a radar scientist at NASA’s Jet Propulsion Laboratory, said in a statement. “We’ll observe the asteroid with both optical and radar telescopes. With radar observations, we might be able to see surface details that are only a few meters in size.”
