What's Up: October 2024 Skywatching Tips from NASA

NASA is back again with its monthly update of celestial delights to enjoy over the coming weeks. The space agency shared its tips in a video (above), which we’ve summarized below.

Planets galore!

It turns out that October offers a great chance to spy many of the planets in our solar system. Here’s a quick look at what you can see and the best time to look:

Venus: The second planet from the sun is viewable this month low in the west just after sunset, and it’s setting by the time the sky is fully dark.

Saturn: The second-largest planet in our solar system is visible toward the southeast as soon as it gets dark, and it sets by dawn.

Mars: The red planet rises around midnight throughout this month. By dawn, it will have climbed quite high into the south-southeastern sky, appearing together with Jupiter.

Jupiter: The largest planet in our solar system is rising in the first half of the night, and in early October, it’ll be high in the south as dawn approaches. Later in October, it will have progressed farther over to the west before sunrise.

Europa Clipper mission

NASA is aiming to launch its latest solar system exploration mission to one of the giant planet’s moons — Europa — as early as October 10.

“It’s thought that Europa holds an enormous ocean of salty liquid water beneath its icy surface,” the space agency says of the highly anticipated mission. “That makes this the first mission dedicated to studying an ocean world beyond Earth. Europa Clipper is designed to help us understand whether this icy moon could support some form of life, and along the way, it’ll teach us more about the conditions that make a world habitable.”

On the mornings of October 11 and 25, clear skies permitting, you can use a telescope or even a pair of binoculars to observe Europa. “Be sure to have your own peek at Jupiter’s moon Europa this month, as a new NASA mission begins its journey to explore an ocean in the sky,” NASA says.

Moon and planet pair-ups

The agency also recommends looking out for moon and planet pair-ups this month, as our nearest neighbor appears close to Saturn after dark toward the southeast on the 13th and 14th of the month, and then with Jupiter in the east on the evening of October 20. And that’s not all. On the mornings of October 23 and 24, early risers can view Mars with the moon high overhead in the south.

Comet Tsuchinshan-ATLAS

This month offers a great chance to observe what could turn out to be the brightest comet of the year. It’s the same one that astronauts aboard the ISS have already been capturing with their cameras. Comet Tsuchinshan-ATLAS is currently hurtling through the inner solar system and made its closest pass of the sun just last week. It’ll be its closest to Earth on October 13 and will offer the best viewing opportunities after that, for the rest of the month, low in the western sky, beginning during twilight.

“It will quickly rise higher each subsequent evening, making it easier to observe, but it’ll also be getting a little fainter each night,” NASA said. “As with all comets, predictions for how bright it could get are uncertain. If the comet’s tail is brilliantly illuminated by the sun, predictions show that it could become bright enough to see with the unaided eye. But comets have a way of surprising us, so we’ll just have to wait and see.”

NASA Roman Telescope Launch Featured

The Hubble telescope has an almost legendary status. Over the last three decades, Hubble gave us some of the most spectacular close-ups of the universe ever captured, and now, NASA’s newest space telescope wants to see the bigger picture. The Nancy Grace Roman Space Telescope successfully launched aboard a SpaceX Falcon Heavy from Kennedy Space Center in Florida at 7:26 a.m. EDT on August 30. Roman is now beginning a roughly three-month journey toward the Sun-Earth L2 point, nearly a million miles away, where it will spend its primary five-year mission surveying huge portions of the cosmos.

Roman carries a 2.4-meter primary mirror, the same diameter as Hubble’s, but its Wide Field Instrument can capture a field of view at least 100 times larger than Hubble’s. NASA expects it to use that combination of sharpness and scale to map billions of galaxies, study dark matter and dark energy, and discover enormous numbers of previously unknown worlds.

The Nancy Grace Roman Space Telescope wasn't built to hunt asteroids, but it turns out to be great at it.
Nancy Grace Roman space telescope.

NASA is about to launch a telescope built to unlock some of the universe's biggest mysteries, and it turns out that same design could help protect Earth along the way.

The Nancy Grace Roman Space Telescope is set to launch from Kennedy Space Center on August 30, 2026, with a primary mission focused on studying dark matter and dark energy - the invisible forces shaping galaxies and cosmic expansion. Researchers now say its unique design also makes it unexpectedly effective at spotting dangerous asteroids headed our way (via MIT Technology Review).

The AI boom is coming for the night sky
How Vast's space station will look in orbit.

AI data centers already consume vast amounts of electricity and water on Earth, so Silicon Valley has begun looking somewhere considerably more spacious... literally.

Elon Musk's SpaceX and Jeff Bezos' Blue Origin, along with several other companies, have proposed enormous constellations of satellites designed to operate as orbital data centers. However, environmental groups and former space officials are now warning that putting them into orbit at the proposed scale could have severe consequences for Earth's atmosphere and the night sky.
