Webb Telescope’s Coldest Instrument Reaches Operating Temperature

NASA’s James Webb Space Telescope will see the first galaxies to form after the big bang, but to do that its instruments first need to get cold – really cold. On April 7, Webb’s Mid-Infrared Instrument (MIRI) – a joint development by NASA and ESA (European Space Agency) – reached its final operating temperature below 7 kelvins.

NASA’s Roman Mission Will Test Competing Cosmic Acceleration Theories

NASA’s Nancy Grace Roman Space Telescope will analyze millions of galaxies strewn across space and time. The mission’s enormous, deep panoramas will provide the best opportunity yet to discern between the leading theories about what’s speeding up the universe’s expansion.

How NASA’s Roman Could Help Find Other Earths by Surveying Space Dust

A team of scientists has found that NASA's Roman Space Telescope will be able to measure a specific kind of space dust littered throughout the habitable zones of 74 nearby planetary systems. Finding out how much of this material these systems contain would help astronomers learn more about planet formation and guide the search for habitable worlds.

NASA’s Webb Reaches Alignment Milestone, Optics Working Successfully

Following the completion of critical mirror alignment steps, NASA’s James Webb Space Telescope team expects that Webb’s optical performance will be able to meet or exceed the science goals the observatory was built to achieve.

NASA Invites Media to 59th Annual Robert H. Goddard Memorial Symposium

Media are invited to meet leaders in space exploration at the 59th annual Robert H. Goddard Memorial Symposium, taking place on the campus of the University of Maryland, College Park, from March 23 to 25. Attendees also have the option to watch the symposium online.

Studying the Next Interstellar Interloper with Webb

One of the most exciting findings in planetary science in recent years is the discovery of interstellar objects passing through our solar system. So far, astronomers have confirmed only two of these interlopers from other star systems — 1I/'Oumuamua in 2017 and 2I/Borisov in 2018 — but many, many more are thought to exist.

Capturing All That Glitters in Galaxies With NASA’s Webb

Within the first year of operations, NASA’s James Webb Space Telescope will help researchers complete a more detailed sketch of the stellar life cycle with high-resolution infrared-light images of 19 galaxies.

One Year into the Biden Administration, NASA Looks to Future

Over the past year, NASA has made valuable contributions to Biden-Harris Administration’s goals – leading on the global stage, addressing the urgent issue of climate change, creating high paying jobs, and inspiring future generations.

Simulated Image Shows How NASA’s Roman Could Expand on Hubble’s Deepest View

A team of astrophysicists has created a simulated image that shows how the Nancy Grace Roman Space Telescope could conduct a mega-exposure similar to but far larger than Hubble’s celebrated Ultra Deep Field Image.

NASA’s Webb Telescope Reaches Major Milestone as Mirror Unfolds

NASA’s James Webb Space Telescope team fully deployed its 21-foot, gold-coated primary mirror, successfully completing the final stage of all major spacecraft deployments to prepare for science operations.

Sunshield Successfully Deploys on NASA’s Next Flagship Telescope

The James Webb Space Telescope team has fully deployed the spacecraft’s 70-foot sunshield, a key milestone in preparing it for science operations.

NASA's Webb Telescope Launches to See First Galaxies, Distant Worlds

NASA’s James Webb Space Telescope launched at 7:20 a.m. EST Saturday on an Ariane 5 rocket from Europe’s Spaceport.

NASA’s Webb Telescope Will Have the Coolest Camera in Space

Before the MIRI instrument – one of four scientific instruments aboard the observatory – can operate, it has to be cooled down to almost the coldest temperature matter can reach.

Simulated Webb Images of Quasar and Galaxy Surrounding Quasar

Researchers will examine three active supermassive black holes – known as quasars – their host galaxies, and their neighborhoods for the first time in detail with the James Webb Space Telescope.

NASA's James Webb Space Telescope Primed to Lift the Haze Surrounding Sub-Neptunes

Detailed atmospheric studies will provide key insights into some of the most common – and mysterious – planets known in the galaxy.

Gregory Mosby Jr. connects us to faraway galaxies

Research Astrophysicist Gregory Mosby, Jr. researches how galaxies grow over time, and how supermassive black holes are the center of those galaxies impact those changes. Along with this research, he helps optimize flight detectors for missions like the upcoming Nancy Grace Roman Space Telescope.

NASA’s Roman Mission Will Help Empower a New Era of Cosmological Discovery

A team of scientists has forecast the scientific impact of the Nancy Grace Roman Space Telescope’s High Latitude Wide Area Survey on critical questions in cosmology.

Vice President Harris to Visit NASA Goddard Today, Deliver Live Remarks

Vice President Kamala Harris will visit NASA’s Goddard Space Flight Center in Greenbelt, Maryland today, Nov. 5, to get a firsthand look at the agency’s work to combat the climate crisis and protect vulnerable communities.

NASA Partnership Supports the Next Generation of Space and Science Professionals

NASA's participation in the Mentoring365 program will provide connectivity and access to the next generation of space and science professionals.

NASA’s Webb Will Join Forces with the Event Horizon Telescope to Reveal the Milky Way’s Supermassive Black Hole

During Webb’s first slate of observations, astronomers will use its infrared imaging power to address some of the unique and persistent challenges presented by the Milky Way’s black hole, named Sagittarius A*.

NASA’s Webb Space Telescope Arrives in French Guiana After Sea Voyage

NASA’s James Webb Space Telescope successfully arrived in French Guiana Tuesday, after a 16-day journey at sea.

NASA Confirms Roman Mission's Flight Design in Milestone Review

NASA’s Nancy Grace Roman Space Telescope has successfully passed its critical design review, signaling that all design work is now complete.

Hubble Snapshot of "Molten Ring" Galaxy Prompts New Research

In this particular snapshot, a science discovery followed the release of a Hubble observation of a striking example of a deep-space optical phenomenon dubbed an "Einstein ring."
