How NASA’s Roman Space Telescope Will Illuminate Cosmic Dawn

Today, enormous stretches of space are crystal clear, but that wasn’t always the case. During its infancy, the universe was filled with a “fog” that made it opaque, cloaking the first stars and galaxies. NASA’s upcoming Nancy Grace Roman Space Telescope will probe the universe’s subsequent transition to the brilliant starscape we see today –– […]

25 Images to Celebrate NASA’s Chandra 25th Anniversary

To celebrate the 25th anniversary of its launch, NASA’s Chandra X-ray Observatory is releasing 25 never-before-seen views of a wide range of cosmic objects. These images, which all include data from Chandra, demonstrate how X-ray astronomy explores all corners of the universe.

Hubble Studies a Potential Galactic Merger

This NASA/ESA Hubble Space Telescope image features the dwarf irregular galaxy NGC 5238, located 14.5 million light-years from Earth in the constellation Canes Venatici. Its unexciting, blob-like appearance seems to resemble an oversized star cluster more than a classic image of a galaxy.

Vivid Portrait of Interacting Galaxies Marks Webb’s Second Anniversary

Two for two! A duo of interacting galaxies commemorates the second science anniversary of NASA’s James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a “parade” of discoveries by astronomers around the world.

Hubble Measures the Distance to a Supernova

Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it’s a difficult one to complete. We can only measure the distances to a few nearby objects like the Sun, planets, and some nearby stars directly. […]

Take a Summer Cosmic Road Trip With NASA’s Chandra and Webb

It’s time to take a cosmic road trip using light as the highway and visit four stunning destinations across space. The vehicles for this space get-away are NASA’s Chandra X-ray Observatory and James Webb Space Telescope. The first stop on this tour is the closest, Rho Ophiuchi, at a distance of about 390 light-years from […]

Hubble Examines an Active Galaxy Near the Lion’s Heart

It might appear featureless and unexciting at first glance, but NASA/ESA Hubble Space Telescope observations of this elliptical galaxy — known as Messier 105 — show that the stars near the galaxy’s center are moving very rapidly. Astronomers have concluded that these stars are zooming around a supermassive black hole with an estimated mass of […]

NASA Releases Hubble Image Taken in New Pointing Mode

NASA’s Hubble Space Telescope has taken its first new images since changing to an alternate operating mode that uses one gyro. The spacecraft returned to science operations June 14 after being offline for several weeks due to an issue with one of its gyroscopes (gyros), which help control and orient the telescope. This new image […]

NASA’s Webb Opens New Window on Supernova Science

Peering deeply into the cosmos, NASA’s James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few […]
