That matches what the astronomers saw and, because our solar system arose from interstellar material, suggests that some of the carbon now in our bodies was once in the form of buckyballs.

But if so, they said, the growth of the black hole still greatly anticipated the growth of the surrounding galaxy, contrary to what astronomers thought previously.

At least six of those x-ray sources — and possibly all 12 — are likely to be what astronomers call x-ray binaries, Hailey says.

These predicted pale stellar halos are very difficult to observe due to their low surface brightness, but IllustrisTNG was able to simulate exactly what astronomers should be looking for in their data.

This is what astronomers expect to see when they look at a distant exoplanet through a polarised filter: nothing (or very little).

And when matter ejected from the second explosion caught up with the debris from the first, the resulting collision produced an extremely bright flash, which is what astronomers observed with SN 2006gy, the team reports in the 15 November issue of Nature.

But other experts say there's a big difference between water vapor, as discovered in HD 189733b's atmosphere, and liquid water, which is what astronomers are really hoping to nail down.

But this would disagree with what astronomers have observed.

Based on those observations, reported in the current issue of The Astrophysical Journal, the authors confirm what astronomers had been thinking about HD 80606b.

Visible light can't pierce Venus's thick shroud of clouds, so most of what astronomers know about the planet's surface comes from observations in radar and other wavelengths.

Previously rendered only in artists» conceptions, the first asteroid collision known in modern times revealed itself in a tail of debris streaming from what astronomers at first assumed was a comet.

At present, the edge of the heliosphere holds up a dense sheet of gas, what astronomers call the «hydrogen wall.»

The model's close match to what astronomers observe is «surprising,» says astrophysicist Mitchell Begelman of JILA at the University of Colorado in Boulder.

What astronomers did not know was whether there were any supernova explosions close enough to Earth in that time period.

These results are consistent with what astronomers have observed from other Wolf - Rayet systems.

Most of what astronomers know about Ceres comes from indirect measurements of its mass and density, based on the way it subtly tugs on Mars and vice versa.

New images from the Cassini space probe show what astronomers are calling «a rubble - pile moon.»

AzTEC - 3, which is located in the direction of the constellation Sextans, is what astronomers refer to as a submillimeter galaxy, since it shines brightly in that portion of the spectrum, but is remarkably dim at optical and infrared wavelengths.

These discs, rather than the hole itself, are what astronomers see.

It isn't easy creating a map of something invisible, but that's what astronomers did earlier this year when they unveiled the largest - ever survey of dark matter.

Because the gas would have remained frozen within the comet's interior unless exposed by the impact, that suggests the probe did penetrate some sort of icy layer — but perhaps one much different from what astronomers originally predicted.

This result reflects what astronomers see close to the galactic centre, where there seem to be very few lightweight stars.

Kepler watches for extremely slight dips in the amount of light coming from a star, a possible indication that a planet is passing across the star's face in what astronomers call a transit.

Venus orbits the Sun, but not exactly on the same plane as the Earth, so it only passes directly between us and the Sun — what astronomers call a transit; think of it as a «mini-eclipse» — every century or so (and then, due to the odd dance of gravity, it happens in pairs separated by 8 years).
