Sentences with phrase «in zodiacal»

Pollux, also called Beta Geminorum, brightest star in the zodiacal constellation Gemini.

Not exact matches

Starting with the total amount of observed infrared light, the researchers had to subtract the so - called zodiacal light produced by dust within our solar system and infrared light from stars and dust in the rest of our galaxy.

Dust of this kind is also the origin of the zodiacal light in the Solar System.

From dark clear sites on Earth, zodiacal light looks like a faint diffuse white glow seen in the night sky after the end of twilight, or before dawn.

The HOSTS Survey has determined that the typical level of zodiacal dust around other stars — called «exo - zodiacal dust» — is less than 15 times the amount found in our own solar system's habitable zone.

«If we want to study the evolution of Earth - like planets close to the habitable zone, we need to observe the zodiacal dust in this region around other stars,» said Steve Ertel, lead author of the paper, from ESO and the University of Grenoble in France.

«The high detection rate found at this bright level suggests that there must be a significant number of systems containing fainter dust, undetectable in our survey, but still much brighter than the Solar System's zodiacal dust,» explains Olivier Absil, co-author of the paper, from the University of Liège.

Exo - zodiacal dust has been warmed to room temperature by its host star, so it glows when viewed in infrared wavelengths — that is, in infrared light, emitted by heated objects.

Remarkably, this zodiacal formation actually resembles the beast it's supposed to portray — a rare species in the sky's largely imaginary zoo.

The dust that orbits in the plane of our solar system is known as «zodiacal dust.»

«Our result is that there is no fundamental problem,» said Steve Ertel of the University of Arizona's Steward Observatory, instrument scientist for the Large Binocular Telescope Interferometer and lead author on the paper, «The HOSTS Survey — Exo - Zodiacal Dust Measurements for 30 Stars,» which is published in the in the Astronomical Journal.

The zodiacal light can be obvious in rural areas, especially in the southern states and in the tropics.

Previous studies had suggested that much of the zodiacal light came from the dust of colliding asteroids, but the only way this model could reproduce the great breadth of the zodiacal cloud above and below the plane of the planets was to have the dust come from the comets that orbit in the vicinity of Jupiter's orbit.

Nesvorný and his colleagues followed particles released in their model from various types of comets or from asteroids and compared the particles» fates with observations of the zodiacal dust cloud.

To make the modeled zodiacal cloud as dense as the real one, the dust had to come from comets falling apart, not just those shedding dust near the sun, the team reports in the 20 April issue of The Astrophysical Journal.

Indeed, Earth is inside a very bright solar system: sunlight scattered by all the dust in the plane of Earth's orbit creates the zodiacal light radiating across the optical spectrum down to long - wavelength infrared.

By adopting a new fitting method based on the total brightness, we have succeeded in reducing the residual levels after subtraction of the zodiacal emission from the AKARI data and thus in improving the modeling of the zodiacal emission.

We therefore aim to improve th... ▽ More The zodiacal emission, which is the thermal infrared (IR) emission from the interplanetary dust (IPD) in our Solar System, has been studied for a long time.

The Zodiacal Light is more easily seen at locations near to the equator and Birkeland hoped his research in Africa might provide the proof he needed for his auroral theories.

Birkeland traveled to Egypt and Sudan to study the Zodiacal Light — a subtle light effect seen in night skies created by sunlight scattered off small particles orbiting the sun.
