On January 3, the Solar Orbiter spotted Mercury passing in front of the Sun. The transit of the small, dark orb puts the scale of our solar system into sharp relief.
A new Webb Space Telescope deep field image shows the luminous realm of Pandora’s Cluster (Abell 2744), a pileup of galaxy clusters that formed over the course of 350 million years.
The Event Horizon Telescope, which brought us the first-ever image of a black hole and the first view of the supermassive black hole at the center of our galaxy, has inspected a much brighter target: a quasar.
Researchers observing a background star pass behind Quaoar, a dwarf planet in the Kuiper belt, found that the distant object has a ring system unlike any previously found in our solar system.
One of the solar system’s 1.1-million-plus asteroids was recently spotted by the Webb Space Telescope, from a distance of about 62 million miles. The asteroid is relatively small, making it a showcase of the new space observatory’s sharp vision.
Jupiter is a superstar in our solar system. It’s the biggest, it’s wonderfully gassy, and it now has the most documented moons, clocking in at 92 natural satellites.
Astronomers just directly measured the mass of a lone white dwarf using the Hubble Space Telescope for the first time. The dwarf—the core remnant of a star—is named LAWD 37, and it burned out about a billion years ago.
The universe has no shortage of oddities, and researchers at the National Science Foundation’s NOIRLab have observed another one in the form of a particular binary star system. The system, called CPD-29 2176, will eventually trigger a kilonova, a celestial event in which two neutron stars collide in a massive…
Astronomical phenomena tend to occur over timespans that dwarf our human scale—a galaxy changes over millions and billions of years, not decades.
The European Space Agency has released its image of the month for January, and it is (perhaps unsurprisingly) a stunning shot from the Webb Space Telescope.
