In 2022, NASA will launch a mission to the asteroid known as 16 Psyche. It's our first mission to a world that isn't primarily rocky or icy, but instead metallic. Scientists have said Psyche might be the exposed metal core of an early planet that failed to form. They've estimated its worth at $10,000 quadrillion. Now a new study suggests something else. Asteroid Psyche might not be as expected. It might not be as metallic or as dense as scientists once thought. Instead, these scientists are calling Psyche a rubble pile. Read more.
There’s no simple way to tell if a wild mushroom is poisonous. To know for sure, you have to identify it and learn about it. The number of edible species varies by location. For instance, the Alabama Mushroom Society lists 18 common edible mushroom species. But beware. A few edible species have poisonous look-alikes.

The sun actually takes more time to set around the time of a solstice than around the time of an equinox. Here's why. This photo shows a June solstice sunset in 2018, captured in the nation of Oman on the Arabian Peninsula, from our friend Priya Kumar. Thank you, Priya!
View at EarthSky Community Photos. | Eyad Khailany in Erbil, Iraq, captured Nova Hercules 2021 on June 15 and wrote: "Nova Her 2021 lies at the precise position RA 18h 57m 31s, Dec +16° 53′ 40″ (J2000.0), which places it in the far south-eastern reaches of Hercules, right on its boundary with Aquila, to the north-west of bright Altair (alpha [α] Aquilae [Aql])." Thank you, Eyad! Charts and details here. And, in case you're wondering, a nova isn't the same thing as a supernova. You'll find more about what makes a nova in this article on variable stars.
