Rogue planets are free-floating planets that do not orbit a star and instead travel through space. Scientists think they are outcasts from developing planetary systems and may be very numerous throught the galaxy. This illustration shows a rogue planet traveling through space.
This image of the Eagle Nebula showcases the superb resolution and wide field of view of NASA’s upcoming Nancy Grace Roman Space Telescope. In the center is Hubble's view of the Pillars of Creation - superimposed on a ground-based image. Roman’s Wide Field Instrument field of view is highlighted. Roman’s images will have the resolution of Hubble while covering an area about 100 times larger in a single pointing.
The wide field image for the Eagle nebula is a combination between an image taken by NSF’s 0.9-meter telescope at Kitt Peak National Observatory (Credit: T.A.Rector (NRAO/AUI/NSF and NOIRLab/NSF/AURA) and B.A.Wolpa (NOIRLab/NSF/AURA)) and an image by amateur astronomer Liam Murphy.

This simulated image of a portion of the Andromeda galaxy highlights the high resolution, large field of view, and unique footprint of NASA’s upcoming Nancy Grace Roman Space Telescope.

Details of a simulated image of the Andromeda galaxy highlight the high resolution of Roman imagery. Unlike a typical wide field camera, which can cover a large area of sky but cannot reveal fine details, Roman will provide both a large field of view and high resolution. The details shown here each cover about 0.0013 square degrees of sky, the equivalent to a single infrared image from Hubble’s WFC3 camera. The pixel scale is 0.11 arcseconds/pixel.

NASA’s Nancy Grace Roman Space Telescope, will capture the equivalent of 100 high-resolution Hubble images in a single shot, imaging large areas of the sky 1,000 times faster than Hubble. In several months, the Roman Space Telescope could survey as much of the sky in near-infrared light—in just as much detail—as Hubble has over its entire three decades.
Although Roman has not yet opened its wide, keen eyes on the universe, astronomers are already running simulations to demonstrate what it will be able to see and plan their observations.
This simulated image of a portion of our neighboring galaxy Andromeda (M31) provides a preview of the vast expanse and fine detail that can be covered with just a single pointing of the Roman Space Telescope. Using information gleaned from hundreds of Hubble observations, the simulated image covers a swath roughly 34,000 light-years across, showcasing the red and infrared light of more than 50 million individual stars detectable with Roman.

The footprint of the Nancy Grace Roman Space Telescope's Wide Field Instrument on top of the Hubble Legacy Survey.
Hubble Legacy Survey:
This Hubble Space Telescope image represents the largest, most comprehensive "history book" of galaxies in the universe.
The image, a combination of nearly 7,500 separate Hubble exposures, represents 16 years' worth of observations.
The ambitious endeavor, called the Hubble Legacy Field, includes several Hubble deep-field surveys, including the eXtreme Deep Field (XDF), the deepest view of the universe. The wavelength range stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time.
The image mosaic presents a wide portrait of the distant universe and contains roughly 265,000 galaxies. They stretch back through 13.3 billion years of time to just 500 million years after the universe's birth in the big bang. The tiny, faint, most distant galaxies in the image are similar to the seedling villages from which today's great galaxy star-cities grew. The faintest and farthest galaxies are just one ten-billionth the brightness of what the human eye can see.
The wider view contains about 30 times as many galaxies as in the Hubble Ultra Deep Field, taken in 2004. The new portrait, a mosaic of multiple snapshots, covers almost the width of the full Moon. Lying in this region is the XDF, which penetrated deeper into space than this legacy field view. However, the XDF field covers less than one-tenth of the full Moon's diameter.

This composite image illustrates the possibility of a Roman Space Telescope “ultra deep field” observation. In a deep field, astronomers collect light from a patch of sky for an extended period of time to reveal the faintest and most distant objects. This view centers on the Hubble Ultra Deep Field (outlined in blue), which represents the deepest portrait of the universe ever achieved by humankind, at visible, ultraviolet and near-infrared wavelengths. Two insets reveal stunning details of the galaxies within the field.
Beyond the Hubble Ultra Deep Field, additional observations obtained over the past two decades have filled in the surrounding space. These wider Hubble observations reveal over 265,000 galaxies, but are much shallower than the Hubble Ultra Deep field in terms of the most distant galaxies observed.
These Hubble images are overlaid on an even wider view using ground-based data from the Digitized Sky Survey. An orange outline shows the field of view of NASA’s upcoming Nancy Grace Roman Space Telescope. Roman’s 18 detectors will be able to observe an area of sky at least 100 times larger than the Hubble Ultra Deep Field at one time, with the same crisp sharpness as Hubble.

(2011) Astronomers have pushed NASA's Hubble Space Telescope to its limits by finding what they believe is the most distant object ever seen in the universe. Its light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is 13.7 billion years.
