NASA’s June skywatching tips include Mars in the Beehive

What's Up: June 2023 Skywatching Tips from NASA

NASA is back again with its monthly roundup of what to look out for in the sky over the coming weeks.

Kicking right off with Thursday and Friday, Mars finds itself in the Beehive Cluster, a group of stars also known as Praesepe or M44 that’s around 600 light years away.

“The pairing will make for great viewing through binoculars or a small telescope, with a sparkle of faint stars surrounding the rust-colored disk of Mars,” NASA said on its website.

To make it easy to pick out Mars and the Beehive, try one of these excellent astronomy apps on your smartphone.

Throughout this month you you can also witness Mars and Venus appearing to move closer together in the western sky after sunset. NASA notes that a crescent moon will pass through from June 20 through June 22, making for a striking spectacle at dusk on June 21.

Early birds, meanwhile, can catch Saturn and Jupiter rising before dawn. The two planets will be visible in the eastern side of the sky before sunrise throughout June, and on June 14 Jupiter will rise with the crescent moon.

NASA also recommends looking out for Spica and Arcturus, two particularly bright stars.

“Orange giant Arcturus is the brightest star in Bootes, the herdsman,” the space agency explained. “It’s the fourth brightest star in the sky. It’s much closer than Spica, at a distance of about 37 lightyears. It’s also quite an old star, compared to our sun, at an age of 7-8 billion years.”

Finally, NASA notes that June 21 is the Summer Solstice in the Northern Hemisphere, and Winter Solstice in the Southern Hemisphere. This means the longest day for the north in terms of sunlight as our nearest star tracks its highest, longest path across the sky, and the shortest in the south, where the sun stays low. Watch NASA’s video at the top of this page to find out how the summer solstice helped the ancient Greeks 2,200 years ago to calculate the size of our planet with impressive accuracy.

NASA answers all of your questions on the troubled Starliner mission
Boeing's Starliner spacecraft docked at the space station.

NASA has updated an FAQ page on its website with the latest information on the state of Boeing Space’s beleaguered Starliner mission.

With so much speculation surrounding the state of the spacecraft, the page offers a definitive guide on where the mission is at right now.

NASA’s axed moon rover could be resurrected by Intuitive Machines
An illustration of NASA's Volatiles Investigating Polar Exploration Rover (VIPER) on the lunar surface.

Lunar scientists were shocked and dismayed last month when NASA announced that it was canceling work on its moon rover, VIPER. The Volatiles Investigating Polar Exploration Rover was intended to search the moon's south pole for evidence of water there, but NASA said that it had to ax the project due to increasing costs.

This week, an open letter to Congress called the cancellation of the mission "unprecedented and indefensible," and questioned NASA's assertion that the cancellation of the mission would not affect plans to send humans to the moon. Scientists argued that the mission was fundamental to understanding the presence of water on the moon, which is a key resource for human exploration, as well as an issue of scientific interest.

Mars has ‘oceans’ worth’ of water – but it’s deep underground
More than 3 billion years ago, Mars was warm, wet, and had an atmosphere that could have supported life. This artist's rendering shows what the planet may have looked like with global oceans based on today's topography.

One of the key issues for getting humans to Mars is finding a way to get them water. Scientists know that millions of years ago, Mars was covered in oceans, but the planet lost its water over time and now has virtually no liquid water on its surface. Now, though, researchers have identified what they believe could be oceans' worth of water on Mars. There's just one snag: it's deep underground.

The research used data from NASA's now-retired InSight lander, which used a seismometer and other instruments to investigate the planet's interior. They found evidence of what appears to be a large underground reservoir of water, enough to cover the entire planet in about a mile of ocean. But it's inaccessible, being located between 7 to 13 miles beneath the planet's surface. The water is located in between cracks in a portion of the interior called the mid-crust, which sits beneath the dry upper crust that is drillable from the surface.
