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.

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.

Watch NASA’s Mars video of a ‘googly eye’ during solar eclipse
The Perseverance Mars rover took this selfie on Sept. 10, 2021 — sol 198 of the mission – in Jezero Crater after coring into a rock called ‘Rochette.’ Rock core samples from the floor of the crater will be brought back to Earth and analyzed to characterize the planet’s geology and past climate.

As it continues its painstaking search for microbial life on Mars, NASA’s Perseverance rover has also been reporting otherworldly happenings occurring during its adventures.

Just recently, for example, one of its many onboard cameras captured some remarkable footage of a solar eclipse as Phobos -- one of Mars’ two moons -- passed between the red planet and the sun.

See the polar moon sites where NASA plans to land its astronauts

NASA has updated its list of potential landing sites for the next human visit to the moon, which is planned for 2026. The Artemis III mission will see the first crewed lunar landing since the Apollo era, and the plan is for astronauts to explore the moon's South Pole region where there is thought to be water ice on the lunar surface.

NASA shared a list of 13 candidate landing locations for Artemis III in 2022, but has now updated its list to nine candidates. Some of these were on the list previously, while others have been added such as the Mons Mouton mountain and plateau, which is particularly interesting to scientists because the height of the mountain means that there are permanently shadowed regions nearby. These places, where sunlight never touches, are particularly good candidates when it comes to looking for water ice.
