Sentences with phrase «big gas cloud»

Lee thinks the galaxy probably formed not from the cataclysmic collapse of one big gas cloud but from the mergers of many smaller ones.

Not exact matches

He got time on Hubble to observe this strange object, now called Hanny's Voorwerp (which is Dutch for «thing»), and now we think we know what it is: a huge cloud of gas, as big as our own Milky Way, lit up by the nearby spiral!

In the clouds in her model, atmospheric gas would sometimes condense onto the shimmering dust particles, increasing in size to a few millimeters big.

Around the same time, volcanoes a million times bigger than Mount Saint Helens erupted, spewing enormous clouds of dust and gas into the sky and covering the ground with 2 million square miles of molten lava.

But the black holes in the Whirlpool have temperatures of less than 4 million degrees Celsius, indicating that the clouds of hot gas swirling around them are bigger and more spread out.

Just take an interstellar molecular cloud — in essence, a big bag of cold gas and dust — shake it lightly and allow the ingredients to settle.

Nevertheless, those modest - size black holes left a big mark by performing a form of stellar birth control: Radiation from the trickle of material falling into the holes heated surrounding clouds of gas to about 5,000 degrees Fahrenheit, so hot that the gas could no longer easily coalesce.

The big bang produced only hydrogen, helium, and a little lithium, and gas clouds containing only these elements can't cool.

That's according to a new analysis — part of the biggest census of star - forming regions to date — that focused on stars eight times the mass of our sun or larger (the size that eventually explode as supernovae) at a very early stage in their lifetime, when they'd still be inside the clouds of gas and dust where they formed.

Giant gas clouds in the early universe could have powered the most energetic eruptions since the big bang.

Hidden within an interstellar gas cloud like this one, astronomers detected glowing remnants of the big bang.

A team of astronomers has found a gas cloud that existed when the universe was 13 % of its current age that appears to be made of the pristine gas produced in the big bang but with just a wisp of heavier elements: 1/3000 of the level in our solar system.

Now, a new, computer simulation — based study suggests that these giants were formed and fed by massive clouds of gas sloshing around in the aftermath of the big bang.

According to the big bang theory, stars began to form by the gravitational collapse of spinning dust and gas clouds 420 million years after the big bang's sudden inflation.

«It clearly took a while after that primordial explosion for clouds of gas to congeal into a form dense enough for stars and quasars to ignite, and the Sky Survey is already prompting astronomers to question some of the assumptions about how that process unfolded [i.e, the big bang theory].»

In 2011, his team's discovery of pristine clouds of gas formed shortly after the Big Bang was also featured as one of nine runners - up to the «Breakthrough of the Year» in Science magazine in addition to making the Physics World top ten.

In the simulation, clouds of gas left over from the Big Bang slowly coalesced under the force of gravity, and eventually formed the first stars.

The thing to understand about both stars and their solar systems is that they all start out as a big cloud of gas and dust.

Shortly after the big bang about 14 billion years ago, collapsing gas and dust clouds might have lead to the formation of galaxies.

This finding was unexpected, as most current theoretical calculations indicate that it should have been very difficult to form low - mass stars shortly after the Big Bang because heavier elements are needed to efficiently cool gas clouds as they contract into stars (more discussion on the expected mass of Population III stars from Bernard Carr, 1994 versus Richard B. Larson, 1999).

Astronomers looked at it and realized she had spotted something they had never seen before: a gas cloud as big as our solar system, illuminated by energy from a nearby galaxy's black hole [source: Plait].

«I've worked with some of the biggest radio telescopes in the world to image black holes and gas clouds,» says Gugliucci.

When a nebula (a big cloud of gas and dust) collapses, the core forms a hot star.

Both objects formed among the rocky and icy protoplanets beyond the Solar System's «ice line» now located around 2.7 AUs, but the early development of Jupiter apparently prevented such large protoplanets between the gas giant and planet Mars from agglomerating into even bigger planetary bodies, by sweeping many into pulverizing collisions as well as slinging them into the Sun or Oort Cloud, or even beyond Sol's gravitational reach altogether.
