Are you interested in joining the stargazer bandwagon! Well, for that, you do not have to spend a lot of money on buying equipment such as CCD cameras and powerful telescopes. However, you need to be prepared and learn the basics well. Here is a beginner’s guide to stargazing to help you on your journey ...
Nestled among the vast clouds of star-forming regions like this one lie potential clues about the formation of our own solar system. The image below is from the NASA/ESA Hubble Space Telescope and features AFGL 5180, a beautiful stellar nursery located in the constellation of Gemini (the Twins). At the center of the image, a massive star is ...
Using the most advanced telescopes on Earth and in orbit, scientists like Dr. Rebecca McElroy have gained unprecedented access to nearby galaxies, investigating how clouds of cold gas coalesce into hot balls of nuclear fusion giving birth to stars and stunning galactic fireworks. Breathtaking images of galaxies close to the Milky Way have been released ...
University of Arizona researchers have observed, in unprecedented detail and spatial resolution, organic molecules in planetary nebulae, or the aftermath of dying stars. Their work sheds new light on how stars form and die. Using the Atacama Large Millimeter Array, or ALMA, UArizona Regents Professor Lucy Ziurys and her collaborators observed radio emissions from hydrogen cyanide, formyl ...
The Milky Way is a spiral galaxy, which means that it is composed, among other components, of a disc of stars, gas, and dust in which the spiral arms are contained. At first, it was thought that the disc was completely flat, but for some decades now it has been known that the outermost part ...
Massive stars Astronomers commonly refer to massive stars as the chemical factories of the Universe. They generally end their lives in spectacular supernovae, events that forge many of the elements on the periodic table. How elemental nuclei mix within these massive stars has a major impact on our understanding of their evolution prior to their ...
A team including Northwestern University astrophysicists has developed the most realistic, highest-resolution 3D simulation of stars being born to date. The result is a visually stunning, mathematically-driven marvel that allows viewers to float around a colorful gas cloud in 3D space while watching twinkling stars emerge. Called STARFORGE (Star Formation in Gaseous Environments), the computational framework is ...
We are made of stardust, the saying goes, and a pair of studies from University of Michigan research found that may be more true than we previously thought. The first study, led by U-M researcher Jie (Jackie) Li and published in Science Advances, finds that most of the carbon on Earth was likely delivered from the ...
Though our galaxy is an immense city of at least 200 billion stars, the details of how infant stars formed remain largely cloaked in mystery. Scientists know that stars form from the collapse of huge hydrogen clouds that are squeezed under gravity to the point where nuclear fusion ignites. But only about 30 percent of ...
A research team, led by astronomers from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), has discovered 591 high-velocity stars based on data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and Gaia, and 43 of them can even escape from the Galaxy. The study was published online in The Astrophysical Journal Supplement Series. ...
