is located roughly 7.5 billion light-years from Earth. Scientists first dismissed the line as an imaging artifact from Hubble’s cameras. But follow-up spectroscopic observations reveal it is a 200,000-light-year-long chain of young blue stars leading...

is engineered to bridge a specific gap in current astronomical capabilities, functioning as a powerful complement to the Hubble Space Telescope and the James Webb Space Telescope. While existing observatories excel at detailed, high-resolution snapshots...

of how the early Milky Way would have appeared to instruments like the James Webb Space Telescope (JWST) and the Hubble Space Telescope. Testing Physics Through Cosmic Evolution Because humans cannot observe the long-term evolution of a single galaxy in...

1,000 times higher than what is observed in our own solar system relative to calcium. By analyzing archival data from the Hubble Space Telescope, the Far Ultraviolet Spectroscopic Explorer, and the Very Large Telescope, the team determined that these...

yet its central region has long eluded detailed study because thick dust lanes absorb visible light. Prior surveys with the Hubble Space Telescope and the now‑retired Spitzer telescope mapped portions of the system, but they lacked the combined...

honoring her legacy in establishing space‑based observational science. Its primary mirror rivals the size of the Hubble Space Telescope, yet its instruments deliver a substantially broader field of view. Positioned within a schedule of forthcoming...

look at the Lion Nebula, also known as NGC 2392. While the object was famously captured in visible light by the Hubble Space Telescope over two decades ago, Webb’s sophisticated suite of instruments has peeled back layers of cosmic dust to reveal the...
