Stellar dust survey paves way for exoplanet missions

Post by Dragon on Thu Apr 26, 2018 3:59 pm

Veils of dust wrapped around distant stars could make it difficult for scientists to find potentially habitable planets in those star systems. The Hunt for Observable Signatures of Terrestrial Systems, or HOSTS, survey was tasked with learning more about the effect of dust on the search for new worlds. The goal is to help guide the design of future planet-hunting missions. In a new paper published in the Astrophysical Journal, HOSTS scientists report on the survey's initial findings.

This artist's illustration shows what the sky might look like from a planet in a particularly dusty solar system. Dust that orbits a star in the plane of the solar system is called zodiacal dust, and the light reflected and scattered by that dust is called zodiacal light.

The Large Binocular Telescope Interferometer, or LBTI, is a ground-based instrument connecting two 8-meter class telescopes on Mount Graham in Arizona to form the largest single-mount telescope in the world. The interferometer is designed to detect and study stars and planets outside our solar system.

Photographer Justin Ng captured the glow of inner solar system dust scattering sunlight over 3 Indonesian volcanoes, the active Semeru and Bromo plus the dormant Batok. Planets Venus, Saturn and Mercury lie within this field of view.

The beginning of spring is not the only thing to look forward to. You can also catch the zodiacal light. It is best viewed after sunset during the spring and before sunrise during the fall when the Moon is not out.
