NASA Telescopes take a close look at the Brightest Comet of 2018


NASA’s Hubble Space Telescope photographed comet 46P/Wirtanen on Dec. 13, when the comet was 7.4 million miles (12 million kilometers) from Earth. In this visible light image, the comet’s nucleus is hidden in the center of a fuzzy glow from the comet’s coma. The coma is a cloud of gas and dust that the comet has ejected during its pass through the inner solar system due to heating from the Sun. To make this composite image, the color blue was applied to high-resolution grayscale exposures acquired from the spacecraft’s WFC3 instrument.

Don’t Judge an Asteroid by its Cover: Mid-infrared Data from SOFIA Shows Ceres’ True Composition

New observations show that Ceres, the largest body in the asteroid belt, does not appear to have the carbon-rich surface composition that space- and ground-based telescopes previously indicated...

NASA Selects Next Generation Spectrometer for SOFIA Flying Observatory

HIRMES will help researchers determine the location of the raw materials that are the building blocks of life and how their position within the interstellar medium helps planetary systems, like our own solar system, evolve

HIRMES will help researchers determine the location of the raw materials that are the building blocks of life and how their position within the interstellar medium helps planetary systems, like our own solar system, evolve

A team from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has been selected to develop a new, third-generation facility science instrument for the Stratospheric Observatory for Infrared Astronomy, SOFIA. The principal investigator, Samuel Harvey Moseley will lead the team to develop the High Resolution Mid-InfrarEd Spectrometer (HIRMES).

Moseley and his team will construct HIRMES over the next two and one-half years with flights on board SOFIA slated for spring 2019...

NASA’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, has released a new map of the interstellar cloud called the Horsehead Nebula, in constellation Orion. This map is made of 100 separate views of the nebula, each mapping carbon atoms at different velocities. When combined, these different views create a multi-faceted representation of the nebula. Each location on this new SOFIA map of the nebula contains a far-infrared spectrum of the gas and dust there, allowing astronomers to examine the dynamics, chemistry, temperatures, and velocity within the nebula...
