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 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?
The formation mechanism of these structures is connected to the most puzzling questions regarding stellar evolution: What is the role of rotation as matter collapses to form a star, and how does stellar rotation evolve from the birth to the death of stars?Noam Soker...

Where Is the Hubble Telescope and How Does It Work?By: Craig Freudenrich, Ph.D. & Sarah Goddard | Updated: Nov 30, 2023 The Hubble Space Telescope is deployed from the cargo bay of the space shuttle Have you ever stared at the night sky and wondered what the universe looks like up...
How long does it take to cool the Hubble Telescope? How long do planetary nebula glow? What ended planet formation? How long is the precession cycle? How long is the Hubble Space Telescope's orbital period? How long does it take to re-enter the earth's atmosphere? How long is a year...
What is an accretion disk, and how does one form? Why are gas planets round? Are Jovian planets smaller than terrestrial planets? Is Jupiter a Jovian planet? How are dwarf planets different from terrestrial planets? Why do the Jovian planet interiors differ?
Some targets would be the Pleiades, the Hyades, Coma cluster, Alpha Persei cluster, Rosette nebula, Veil nebula, North American nebula, Markarian’s Chain, Kimble’s Cascade. Or any star field in Cygnus, Sagittarius or the Milky Way. That would be a rich field. ...
So let me clarify my confusion, if light emitted by part of a nebula is invisible because it is too dim for my exposure setting - iso/focal ratio/exposure time I have set, does it make a difference if I take one shot or 1000 shots then stack them? I assume I still won’t see th...
Hubble Space Telescope's view of the Crab Nebula supernova remnant.NASA/ESA/STScI Stars Connect Us with the Cosmos Stars exist in billions of galaxies across the universe. They are an important part of the evolution of the cosmos. They were the first objects to form more than 13 billion ye...
