Nebulae are typically characterized by their beautiful and intricate patterns, which are formed from various interstellar materials. These clouds are primarily composed of gas, dust, andplasma, all of which are remnants ofstellar processes, such as the fusion of hydrogen in stars, stellar winds, an...
Nebula play a key role in the life cycle of stars, both at their birth and death. Stars are born in dense clumps of gas, dust, and other material inside diffuse emission nebulae, also frequently referred to as "stellar nurseries". Hubble’s Pillars of Creation is in this category, as...
Emission Nebulae are those that emit spectral line radiation from ionized gas, and are often called HII regions because they are largely composed of ionized hydrogen. In contrast, Reflection Nebulae do not emit significant amounts of visible light, but are still luminous because they reflect the l...
The composition of the ISM is broken down by the scientists at the Infrared Processing and Analysis Center (IPAC) at Caltech: the ISM is mostly composed of atoms of hydrogen (~90%) and helium (~8%), which are the two most common atoms in the universe having been created in the Big ...

A carbon dioxide molecule consists of one carbon atom and two oxygen atoms. Carbon dioxide on Earth and in space CO2is one of the commonest and simplest molecules in the Universe. There are carbon dioxide molecules in outer space, where they formed in nebulae after supernova explosions. ...
Its atmosphere is composed of hydrogen, helium and methane, yet pressure causes about a third of this distant planet to behave as a liquid. Larger telescopes may be able to discern a few of Uranus’ moons, for Titania (the brightest) is around magnitude 14. Let’s begin our lunar ...
