NASA Completes Heart of Roman Space Telescope’s Primary Instrument

LP 791-18 d, shown here in an artist's concept, is an Earth-size world about 90 light-years away. The gravitational tug from a more massive planet in the system, shown as a blue disk in the background, may result in internal heating and volcanic eruptions – as much as Jupiter’s moon Io, the most geologically active body in the solar system. Astronomers discovered and studied the planet using data from NASA’s Spitzer Space Telescope and TESS (Transiting Exoplanet Survey Satellite) along with many other observatories.

The most dust-enshrouded black holes can completely stop X-rays and visible light escaping, but the same dust can be heated by a growing black hole and glow brightly at infrared wavelengths.

Above: Image of the object observed with the Hubble Space Telescope. It shows the emission in the ultraviolet part of the spectrum. Middle: Ultraviolet image of a local galaxy without a bulge and observed edge-on (IC 5249). The similarities are obvious. Bottom: The same galaxy IC 5249 observed in the visible part of the spectrum.

This image of the dusty debris disk surrounding the young star Fomalhaut is from Webb’s Mid-Infrared Instrument (MIRI). It reveals three nested belts extending out to 14 billion miles (23 billion kilometers) from the star. The inner belts were revealed by Webb for the first time. Credit: NASA, ESA, CSA, A.
