By harnessing the capabilities of the 8.1-meter Gemini South telescope in Chile, which is part of the International Gemini Observatory operated by NSF’s NOIRLab, astronomers have obtained the sharpest image ever of the star R136a1, the most massive known star in the Universe.
Short gamma ray bursts are caused by the merger of two neutron stars. However, not all short gamma-ray bursts are associated with galaxies. In this podcast, Brendan O’connor, described recent research into the host galaxies of short gamma-ray bursts.
Quasars are very distant and luminous objects powered by supermassive black holes. Today NORLab discuss about the discovery of the most distant supermassive black hole and quasar & what can we learn from it.
Neptune and Uranus have much in common but their appearances are notably different. Today, @halfastro discuss with Dr. Patrick Irwin about the differences in the colors of Uranus and Neptune.
The Solar System, the Moon and its features, the stars, the constellations, the properties of light, and the preservation of dark skies will be some of the topics featured in the Scholar Astronomy Program, part of NOIRLab’s Star Educators program
The Astronomy in Chile Educator Ambassadors Program (ACEAP) brings amateur astronomers, planetarium personnel, and K-16 formal and informal astronomy educators to US astronomy facilities in Chile. In this podcast, Tim Spuck described the ACEAP program and how interested educators can apply.
The advent of satellite constellations has proven challenging for optical and radio astronomers. The International Astronomical Union (IAU) recently announced the formation of the IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference. This podcast discusses the founding of the center and its mission.
A group of undergraduate students from University of Chicago discover the early universe’s brightest gravitationally lensed galaxy. Learn the fascinating story of how this gravitational lens was discovered and what we can learn about the early universe from this discovery on today podcast.
Modern astronomical cameras capture data in a format called a FITS which cannot be opened by many common image processing programs. Today, Robert Hurt (IPAC) talks about FITS files, the history of FITS Liberator, how you can use FITS Liberator 4 to create your own images and some sources of astronomical data.
The Hubble Constant tells us how fast the universe is expanding. However, different methods of measuring the Hubble Constant give different results. In this podcast, NOIRLab’s John Blakeslee describes data his team has collected to help resolve this discrepancy.
