More Details Emerge About 'Oumuamua, Earth's First-Recorded Interstellar Visitor

In October, scientists using the University of Hawaii's Pan-STARRS 1 telescope sighted something extraordinary: Earth's first confirmed interstellar visitor. Originally called A/2017 U1, the once-mysterious object has a new name—'Oumuamua, according to Scientific American—and researchers continue to learn more about its physical properties. Now, a team from the University of Hawaii's Institute of Astronomy has published a detailed report of what they know so far in Nature.

Fittingly, "'Oumuamua" is Hawaiian for "a messenger from afar arriving first." 'Oumuamua's astronomical designation is 1I/2017 U1. The "I" in 1I/2017 stands for "interstellar." Until now, objects similar to 'Oumuamua were always given "C" and "A" names, which stand for either comet or asteroid. New observations have researchers concluding that 'Oumuamua is unusual for more than its far-flung origins.

It's a cigar-shaped object 10 times longer than it is wide, stretching to a half-mile long. It's also reddish in color, and is similar in some ways to some asteroids in our solar system, the BBC reports. But it's much faster, zipping through our system, and has a totally different orbit from any of those objects.

After initial indecision about whether the object was a comet or an asteroid, the researchers now believe it's an asteroid. Long ago, it might have hurtled from an unknown star system into our own.

'Oumuamua may provide astronomers with new insights into how stars and planets form. The 750,000 asteroids we know of are leftovers from the formation of our solar system, trapped by the Sun's gravity. But what if, billions of years ago, other objects escaped? 'Oumuamua shows us that it's possible; perhaps there are bits and pieces from the early years of our solar system currently visiting other stars.

The researchers say it's surprising that 'Oumuamua is an asteroid instead of a comet, given that in the Oort Cloud—an icy bubble of debris thought to surround our solar system—comets are predicted to outnumber asteroids 200 to 1 and perhaps even as high as 10,000 to 1. If our own solar system is any indication, it's more likely that a comet would take off before an asteroid would.

So where did 'Oumuamua come from? That's still unknown. It's possible it could've been bumped into our realm by a close encounter with a planet—either a smaller, nearby one, or a larger, farther one. If that's the case, the planet remains to be discovered. They believe it's more likely that 'Oumuamua was ejected from a young stellar system, location unknown. And yet, they write, "the possibility that 'Oumuamua has been orbiting the galaxy for billions of years cannot be ruled out."

As for where it's headed, The Atlantic's Marina Koren notes, "It will pass the orbit of Jupiter next May, then Neptune in 2022, and Pluto in 2024. By 2025, it will coast beyond the outer edge of the Kuiper Belt, a field of icy and rocky objects."

Last month, University of Wisconsin–Madison astronomer Ralf Kotulla and scientists from UCLA and the National Optical Astronomy Observatory (NOAO) used the WIYN Telescope on Kitt Peak, Arizona, to take some of the first pictures of 'Oumuamua. You can check them out below.

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

How to Watch SpaceX’s Historic Astronaut Launch Live

NASA astronauts Doug Hurley and Bob Behnken make their way to the SpaceX Falcon 9 rocket with the Crew Dragon spacecraft on launch pad 39A at the Kennedy Space Center on May 30, 2020 in Cape Canaveral, Florida.

After scrubbing its original launch on May 27 due to bad weather, SpaceX will attempt to make history yet again today (May 30) when it launches its first crewed spacecraft from Cape Canaveral, Florida, at 3:22 p.m. EDT. Powered by a Falcon 9 rocket, the Crew Dragon spacecraft will transport NASA astronauts Doug Hurley and Bob Behnken to the International Space Station, marking the company's first-ever crewed mission and the first crewed launch from the U.S. since 2011. If you want to watch the momentous event from home, there are plenty of ways to stream it live online.

Both SpaceX and NASA will be hosting livestreams of the May 30 launch. NASA's webcast kicks off at 11 a.m. EDT today with live looks at the Crew Dragon and Falcon 9 rocket at the Kennedy Space Center. The feed will continue streaming until the afternoon of Sunday, May 31, with the spacecraft set to dock at the International Space Station at 10:29 a.m. EDT. You can catch the coverage on NASA's website, its social media channels (including YouTube), or on the NASA TV channel through cable or satellite. SpaceX's stream will be broadcast on the company's YouTube channel. (You can watch the video below).

Several television networks will be covering the event (check your local listings), and ABC News Live will partner with National Geographic to air "Launch America: Mission to Space Live" at 3 p.m. EDT.

The launch has been scheduled down to the minute, but SpaceX still has time to change that depending on the weather. Wednesday's launch was canceled less than 17 minutes before liftoff, and SpaceX founder Elon Musk has already tweeted that there's a 50 percent chance that weather could prove problematic once again. If today's launch doesn't happen according to plan, there is another window set aside for a third attempt tomorrow, Sunday, May 31, at 3 p.m. EDT, with CNN reporting that the odds of cooperative weather being slightly higher—about 60 percent—for tomorrow.
