A nebula ais one of the most beautiful deep-sky objects in the night sky. But what is a nebula? And how do these space clouds form?
How was VY Canis Majoris formed? How does the Nebular therory explain the Oort cloud? How is Jupiter different from other planets? What are planetary systems made of? Why is Pluto not considered a Jovian planet? What is Neptune's atmosphere made of?
Spiral Planetary: The term "planetary nebula" was coined by William Herschel in the 1700s, and originally referred to any extended object that resembled a planet when viewed through the telescope. Answer and Explanation:1 Spiral Planetary Nebula is also referred to as NGC 5189. It is estimated...
One of the most famous star-forming regions visible to our eyes (and telescopes) is the Orion Nebula. A stellar nursery, it's a hotbed for newborn stars and provides a glimpse into the various stages of star birth. Whether you're looking at a Hubble image or gazing through a telescope,...
A light wave consists of electromagnetic energy. The size of a wave is measured by its wavelength. The wavelengths of the light we can see range from 400 to 700 billionths of a meter (nanometers). The amount of energy in a light wave is proportionally related to its wavelength: shorter ...
At the centre of the Southern Ring Nebula is a hot, dense white dwarf star. As it transformed into a white dwarf, the star periodically ejected mass – the shells of material you see here. ©NASA/ESA/CSA/STScI Much of the heat that was generated in the core throughout the Sun’s...
What is the core accretion model? Artist's conception of our solar system's solar nebula, the cloud of gas and dust from which Earth, the sun and our solar system's other planets planets formed. (Image credit: Painting copyright William K. Hartmann, Planetary Science Institute, Tucson) Appr...
potassium were similar to other terrestrial planets. While thorium is a stable element, potassium is more volatile, easily baked away by higher temperatures. MESSENGER's findings suggest that the planet was not subjected to extreme heating or early evolution but formed much like other terrestrial ...
that helium hydride had to be the first molecule that ever formed in the universe ... and yet, it didn't exist anywhere on Earth. The breakthrough finally came in 2019, when a study published inNaturedemonstrated the presence of helium hydride in a planetary nebula 3,000 light years away...
Hubble is turning 35: Here are its best images from the last year Beautiful Hubble image shows the stunning colors of the Veil Nebula A 200,000 light-year wide monster jet from the early universe The findings are relevant to the early universe because, like early galaxies, there are relative...
