Check out NASA’s top skywatching tips for this month

NASA has just shared its monthly update on what to look out for in the night sky.

What's Up: October 2021 Skywatching Tips from NASA

October looks to be a busy time, with our moon, several planets, and a few stars all featuring in the space agency’s list of highlights.

It’s worth noting that the recommendations below can be enjoyed with the naked eye, so no fancy equipment is needed. Having said that, if you have binoculars or a telescope at hand, by all means, use them to enhance your skywatching experience. Spotting stuff in the night sky can also be made easier using one of the many available astronomy apps.

Moon, Venus, and Antares

NASA kicks off with a recommendation to look out for the 5-day-old crescent moon on October 10 as it joins Venus and orange-colored Antares, one of the brightest stars in the night sky. A few days later, on October 15 and 16, Venus will appear to move closer to Antares, offering skywatchers a chance to enjoy two prominent celestial bodies side by side.

Two bright stars

Early in the evening throughout October, you’ll be able to see two bright stars that alternate with Polaris to be the North Star.

Vega and Deneb, as they’re called, form two parts of the so-called Summer Triangle, with the third star being Altair. You can see the stars by looking directly overhead during the first few hours after nightfall. “They’ll be two of the brightest stars you can see up there,” NASA says.

Vega is a bluish-white star that turns quickly, performing a complete rotation every 12.5 hours (our own sun turns once every 27 days). Deneb is described as a “blue-white supergiant star that is fusing hydrogen at a phenomenal rate,” suggesting to scientists that it’ll likely meet a spectacularly explosive end as a supernova “within a few million years.”

Mercury

During the last week of October, Mercury, the closest planet to the sun, will make an appearance, though you’ll have to get up early to catch it.

“Look for it about 10 degrees above the eastern horizon, or about the width of your fist held at arm’s length, about 30-45 minutes before sunrise,” NASA says in the video.

For more on Mercury, check out these amazing images captured just recently by the BepiColombo mission as it made the first of six flybys of the planet.

Finally, NASA notes that October 16 is International Observe the Moon Night, a global event that encourages everyone to find out more about the science and exploration of our nearest neighbor.

NASA’s Crew-7 astronauts splash down safely off the coast of Florida

NASA's Crew-7 mission has splashed down without incident off the coast of Florida, with the four astronauts on board returning safely from the International Space Station (ISS). The crew spent a total of 199 days orbiting the Earth and are now headed to NASA’s Johnson Space Center in Houston to rest and recover.

The crew traveled in a SpaceX Dragon capsule that undocked from the ISS on Monday, March 11, and splashed down at 5:47 a.m. ET on Tuesday, March 12. The group arrived at the station in late August 2023, and spent their time in orbit performing research and maintenance tasks.

The first crewed test flight of Boeing Space’s CST-100 Starliner spacecraft has been delayed yet again, but this time it’s not the result of an issue with the vehicle itself.

Meet NASA’s trio of mini moon rovers set to launch next year

NASA is ramping up its plans for exploring the moon, not only in terms of preparing to send astronauts there but also rovers. There's the VIPER rover, which will search for water around the lunar south pole, and now NASA is introducing a trio of mini rovers called CADRE, or Cooperative Autonomous Distributed Robotic Exploration. These will work together as a team to map the lunar surface, testing the possibilities of using rovers in groups for future exploration.

The rovers, developed at NASA's Jet Propulsion Laboratory, are just the size of a carry-on suitcase. They are designed to move independently but share data so they can cover more ground than a single rover could. They'll have to work over a lunar day, which is about two weeks, to map out features on the surface and look below ground using radar.
