The emergence of chemistry had a transformative effect on the universe because of a peculiar property of atomic hydrogen: If you take a big cloud of hydrogen atoms and let it collapse, it gets hotter and hotter until all the bound - up energy keeps it from shrinking any further.

He says this might be the most interesting epoch of all — a time when the primordial clumps of hydrogen took shape, becoming the clouds from which the first stars and galaxies would eventually form.

«Immense cloud of hydrogen discovered escaping from exoplanet the size of Neptune.»

Using the Very Large Array of the National Radio Astronomy Observatory in the US, the team observed radio emission from hydrogen in a distant galaxy and found that it would have contained billions of young, massive stars surrounded by clouds of hydrogen gas.

Now images taken by the Hubble Space Telescope have revealed a large cloud of hydrogen and oxygen — most likely in the form of water vapour — extending from the moon's south pole.

The images of infrared light coming from glowing hydrogen show that the cloud was compact both before and after its closest approach, as it swung around the black hole.

Instead of searching for the light from individual galaxies with an optical telescope, the team stalked a different quarry, red - shifted radio waves emitted by hydrogen atoms floating in huge clouds within the galaxies.

If so, astronomers could hunt for them by detecting gamma rays, neutrinos, and even antimatter radiating from interstellar and intergalactic clouds of hydrogen gas.

They found a large cloud of hydrogen and oxygen extending from the moon's south pole.

They could have condensed directly out of seed clouds of hydrogen gas weighing tens of thousands of solar masses, and grown from there by gravitationally swallowing up more gas.

Comets are surrounded by a huge cloud of atomic hydrogen because water (H2O) vaporizes from the icy nucleus, and solar ultraviolet light breaks it apart into hydrogen and oxygen.

The lack of absorption features means that GJ 1214 b can not have a diffuse hydrogen atmosphere unless it also has a high cloud layer that blocks the starlight from streaming through.

This artist's concept shows «The Behemoth,» an enormous comet - like cloud of hydrogen bleeding off of a warm, Neptune - sized planet just 30 light - years from Earth.

This could mean that the system formed from interstellar gas clouds that were richer in hydrogen and helium than the ones typically found in our Galaxy, and that were poorer in heavy elements — which astronomers call metals.

Detailed radio maps of nearby molecular clouds reveal that they are clumpy, with regions containing a wide range of densities — from a few tens of molecules (mostly hydrogen) per cubic centimetre to more than one million.

«The latest data confirm these results and show that instead of trailing away smoothly from the Galactic plane, a significant fraction of the hydrogen gas in the halo is concentrated in discrete clouds.

Based on the extreme, deduced photometric redshift of GRB 000131 indicating that the gamma rays had travelled an extreme long cosmological distance, astronomers predicted a «break» in the red region of the spectrum around 670 to 700 nm from the strong absorption of light from intervening intergalactic hydrogen clouds along the line of sight between GRB 000131 and the Solar System.

Photo Source: S. Brunier; Design & Illustration: P. Vosteen (CC BY - ND) A team of astronomers has discovered what appears to be a grand exodus of more than 100 hydrogen clouds streaming away from the center of the Milky Way and heading into intergalactic space.

This region of sky includes glowing red clouds of mostly hydrogen gas, blue regions where starlight is being reflected from tiny particles of dust and also dark regions where the dust is thick and opaque.

Astronomer Vera Cooper Rubin found over decades of radio observations that the rotational velocity of clouds of ionized hydrogen (HII regions) in spiral galaxies like the Milky Way was not decreasing at increasing distance from their galactic cores, like the velocity of the planets around the Sun.

The earth has some 1.33 x 10 ^ 50 atoms in it, almost none of it hydrogen or helium, so all of its atoms must have come from another star's supernova dust cloud.

For example, the passage of the heliosphere through a cloud with a neutral hydrogen density of 11 cm − 3 rather than the present value of about 0.2 cm − 3 would shrink the termination shock from about 90 AU in the upwind direction to only 14 AU.»
