   After a supernova, some stars leave behind a super dense neutron star, while the heaviest stars leave a black hole. Based on our understanding of stellar evolution, the Sun will start to run out of core hydrogen in about 5 billion years. The Sun will expand, engulfing several of the inner planets, including Earth.

   Dec 29, 2022 · Despite what we normally see here on Earth, red stars are cooler. They are still very hot, but cool in relation to other stars. The smallest and coolest stars are typically red with red dwarfs being as small as 10% of the mass of our Sun and emitting only 0.01% of our Sun’s energy at only 3,000-4,000 degrees Kelvin (4,940-6,740 F or 2,727 ...

   Oct 13, 2023 · Within these now-active nebulae, particles collide and start to form clumps. As these clumps accumulate more material, they grow in mass. Thanks to their own gravity, they pull in even more gas and dust from the surrounding star-forming region. Over a million years (give or take), these clumps mature into dense bodies known as protostars.

   Aug 13, 2009 · Cepheus B, a molecular cloud located in our Milky Galaxy about 2,400 light years from the Earth, provides an excellent model to determine how stars are formed. This composite image of Cepheus B combines data from the Chandra X-ray Observatory and the Spitzer Space Telescope. A molecular cloud is a region containing cool interstellar gas and ...

   How do stars form?

   • Stars form in clouds of gas and dust called nebulae or stellar nurseries that can form anywhere between a few dozen to thousands of stars. As particles of dust are attracted to each other, blobs or knots of gas and dust begin to form and spin around each other.

   How did Earth become a planet?

   • Early in its evolution, Earth suffered an impact by a large body that catapulted pieces of the young planet's mantle into space. Gravity pulled many of these pieces together to form the moon, which took up orbit around its creator. The late-stage phase of planet formation with protoplanets and planetismals is seen in this artist's depiction.

   How did Earth start?

   • At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.

   What is star formation?

   • Star formation is a complex process, beginning from cold clouds of gas and dust and ending with the diverse population of stars we observe in our galaxy and beyond. Studying that process requires many different types of astronomical observations to capture the composition, dynamics, and other properties of star-forming regions.

   How do stars ionize?

   • They find a complex interplay between gravity pulling material toward the young star and radiation pressure pushing it out. Gas and dust form a circumstellar disk that continually accretes onto the star. But as more material falls onto the star, it heats up and ionizes the surrounding gas.

   How do stars evolve?

   • They all have their unique paths of stellar evolution, influenced by their mass, surrounding gas and environment. 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.
