Jupiter comes to opposition on August 20th, when it will shine brighter and closer than at any other time this year. With nights starting earlier and cooler temperatures arriving, there's no better time to make the most of the planet.
New research reveals that Saturn, like Jupiter, has a “fuzzy” core that extends 60% of the way to its surface, a finding that is changing how astronomers think about giant planets.
A new study suggests that wind, not water, created the rock layers in Gale Crater, where the Curiosity rover roams.
While many astrophotographers follow the "rule of 500" (or 300), some experimentation can help find the right exposure time for your setup.
No one knows why quasars flicker — but astronomers are using these wavering beacons to "weigh" the black holes that power them.
The Moon waxes from first quarter to gibbous in the evening sky, offering some of its most interesting telescopic aspects. Venus grows more insistent in the western twilight. And Jupiter and especially Saturn pose well in the southeast to south by late evening.
Perseverance came up empty on its first attempt to grab and stow a sample of Mars.
Careful measurements using the OSIRIS-REX spacecraft have refined astronomers’ predictions for how likely it is that this potentially hazardous asteroid will strike Earth.

Red dwarf stars appear to flare preferentially at high latitudes, which might keep their exoplanets habitable instead of hellish.
The recurrent nova RS Ophiuchi just went into outburst — its first burst in 15 years — and it's bright enough to see with the naked eye

The spent rocket booster that deployed the Russian Spektr-R satellite a decade ago is now set to burn up over the Indian Ocean on Monday, August 9th.
It's Perseid meteor week! Venus lights the western twilight. Saturn and Jupiter are up in the southeast by mid-twilight and await your telescope later at night. And explore the deep-sky glories of Sagittarius before moonlight returns.
It’s August and that means the Perseid meteor shower! One of the year’s most beloved celestial events peaks on Wednesday night−Thursday morning, August 11–12.
Astronomers have discovered the two reddest objects in the asteroid belt, and their origin story might tell us more about planet formation.
With no interference from the Moon, this year's Perseid meteor shower should be excellent. Find a dark location and enjoy every flash.
