These are the top space stories this week from Space.com.
This Saturday, July 4, Earth will be at the farthest point in its orbit around the sun, also known as aphelion.
A high-powered telescope array has caught the brilliant fireworks-like "streamers" of gas formed during an early stage of star development in a cluster.
Astronomers have found a way to pinpoint our solar system's center of mass to within a mere 330 feet (100 meters), a recent study reports.
This elevation map of Jezero Crater on Mars shows the site in a rainbow of colors, with lighter colors representing higher elevation.
Quantum effects are pushing us around all the time, and we now have observational evidence of this somewhat disconcerting fact.
Astronomers have spotted the exposed core of a massive alien planet, an unprecedented find that could shed considerable light on planet formation, evolution and diversity.
Betelgeuse's weird recent dimming was caused by starspots that temporarily covered at least half of the red supergiant's surface, a new study suggests.
Two incredibly strange celestial objects whose discoveries trace, in part, to observatories at the summit of Maunakea now carry the peak with them in official names inspired by Hawaiian culture.
NASA has delayed the launch of its Mars rover Perseverance again, this time to no earlier than July 30, due to rocket preparation delays.
The Hubble Space Telescope will be honored on a new golden dollar coin reflecting the innovation embodied by the orbiting observatory and the U.S. state from where it is managed on the ground.
The Asteroid Foundation is hosting a five-hour series of panels and talks today to examine the state of asteroid research for Asteroid Day 2020.
An unstable massive star has suddenly vanished from view, and astronomers aren't sure if it collapsed into a black hole or is playing peek-a-boo behind galactic dust.
One is blinding white and the other a dull, dusty red. But both are cold, barren worlds, difficult to reach and full of tantalizing scientific mysteries.
It's right there in the name: black holes aren't supposed to produce flashes of light. But scientists think that last year, they spotted black holes doing just that.
In our neighborhood, three quarters of planets have at least one moon, but no such object has been confidently discovered so far in distant star systems — such worlds are just too small and far away.
The Hubble Space Telescope spotted a bat signal out in the cosmos, 1,300 light-years from home. And the bat? It's flapping its wings.
