Zoom in on the Milky Way’s galactic bulge, a densely packed region of stars that also houses our galaxy’s supermassive black hole. Its crowded field of view is useful for detecting objects, typically stars, that pass between us and the bulge using a phenomenon known as microlensing. In this process, an intervening object warps the light from a background star in the bulge. Astronomers theorize that this technique will reveal more than a thousand new exoplanets, some free-floating and some orbiting stars.

A team of astronomers utilized the Hubble Space Telescope to observe the same region that the Nancy Grace Roman Space Telescope will in its Galactic Bulge Time-Domain Survey, which will enable a more thorough analysis of these microlensing events.

When a star wanders too close to a supermassive black hole, it can be shredded in a process known as a tidal disruption event (seen here in an artist’s concept).

Technicians have completed the construction of the Nancy Grace Roman Space Telescope at NASA's Goddard Space Flight Center in Maryland.

The James Webb and Nancy Grace Roman space telescopes will combine their unique capabilities to expand what we know about the universe.

Webb’s giant mirror, ultracold instruments, and infrared vision help it to probe new depths of knowledge about the universe.

Roman has a large field of view and will capture giant, 300-megapixel images, enabling it to survey the sky 1,000 times faster than the Hubble Space Telescope in near-infrared light.

Engineers at NASA's Kennedy Space Center in Florida raised the Nancy Grace Roman Space Telescope from horizontal to vertical, signaling preparations are moving forward for upcoming inspections, functional testing, and integration work.

Hidden neutron stars may soon come into view with the Nancy Grace Roman Space Telescope.

These ultra-dense stellar remnants are often nearly impossible to detect on their own. But when one passes in front of a distant star, its gravity bends the distant star's light, making it appear brighter and slightly shifted in position, a phenomenon known as gravitational microlensing.

Roman will measure both the apparent brightening and the tiny positional shift of these background stars with unprecedented precision, allowing astronomers to not only detect isolated neutron stars, but possibly determine their weight.

While the Nancy Grace Roman Space Telescope will be able to show us more galaxies than have ever been seen before, it’s how the observatory will work with the Hubble and James Webb space telescopes that astronomers are excited about.

Scientists will be able to use Roman’s surveys of the sky to pick interesting objects to follow up on with Hubble and James Webb space telescopes in detail, demonstrating how the observatories will work together.

Revealing the cosmic web: The Nancy Grace Roman Space Telescope will map millions of galaxies and find bubble-like voids, some as small as just 20 million light-years across. Roman’s vast trove of data will give scientists a greater understanding of how cosmic voids are sculpted by dark energy and gravity.
