ASTRONOMY

What are some skywatching highlights in July 2022? The naked-eye planets of dawn – Venus, Mars, Jupiter, and Saturn – dominate the sky, appearing more spread out each morning. Next, if you're feeling the July heat, note the origin of "the dog days" of summer has to do with the bright star Sirius. Finally, if you can find a certain teapot-shaped pattern of stars in the evening, you'll be looking toward the center of the Milky Way. 0:00 Intro 0:11 Morning planet lineup 0:40 Sirius and the "dog days" of summer 1:50 The Teapot and Milky Way core 3:11 July Moon phases Additional information about topics covered in this episode of What's Up, along with still images from the video, and the video transcript, are available at https://solarsystem.nasa.gov/skywatching/home.

This video starts with a view of the star-forming region 30 Doradus, also known as the Tarantula Nebula, in optical wavelengths, taken with ESO’s 2.2-metre telescope at La Silla Observatory. Located in the southern constellation of Dorado (The Dolphinfish) in the nearby Large Magellanic Cloud, the Tarantula Nebula is known for its unique, web-like clouds. During the video, the image shifts to an infrared view of the Tarantula Nebula. The infrared data are provided by ESO’s Very Large Telescope (VLT) and the Visible and Infrared Survey Telescope for Astronomy (VISTA) and reveal pinkish clouds of hot gas. Radio data taken by the Atacama Large Millimeter/submillimeter Array (ALMA) are then overlaid, represented by bright red-yellow streaks. These streaks highlight the locations of cold, dense gas clouds that have the potential to collapse and form new stars. The radio data are then presented on their own, displaying in detail some of the spidery structures that originally gave rise to the moniker Tarantula Nebula.

SpaceX's Starship rocket is nearing first orbital tests. This Super Heavy launch vehicle promises to lift enormous masses into space, and do so at far cheaper costs than the competitors. What could these capabilities do for astronomy though? Join us today as we explore the potential transformative power of Starship for astronomy.

Larry Gladney, Yale – Astronomy in the Time Domain In this talk with the Westport Astronomical Society I will discuss how The Rubin Observatory Legacy Survey of Space and Time (LSST) is designed to survey the entirety of the observable Southern hemisphere sky every three nights for a period of ten years. This mission will produce, starting in 2023-24, an unprecedented astronomical data set for studies of the deep and dynamic universe, make that data widely accessible to a diverse community of scientists, and engage the public to explore the Universe along with science-interested people from around the world. The Rubin Observatory is unique among large telescopes (those with 8-meter class primary mirrors) in that it will have a very wide field of view and the largest prime focus digital camera ever created. The camera is expected to take more than 200,000 pictures per year and ultimately produce a 500 petabyte dataset of images and data products. Larry Donnie Gladney is an American experimental particle physicist and cosmologist. In 2019, he became Professor of Physics and the Phyllis A. Wallace Dean of Diversity and Faculty Development at Yale University Previously he was the Edmund J. and Louise W. Kahn Professor for Faculty Excellence, and Associate Dean for Natural Sciences, at the University of Pennsylvania. His research has focused on issues relating to the origins of expansion of the universe following the Big Bang, and on fundamental connections between matter, energy, space, and time. The recipient of many fellowships and prizes, and a former visiting scholar at the Lawrence Berkeley National Laboratory, Gladney featured in a 2006 oral history conducted by HistoryMakers, a digital archive project preserved at the Library of Congress, which aims to document the contributions of African-Americans to U.S. history and American society.

✨ What's in the Night Sky: May 2022 ✨ 🪐 Planetary Conjunction of Jupiter and Venus 🌠 Eta Aquarids Meteor Shower 🌗 Lunar Eclipse ♒ Constellation of the Month: Aquarius, the Cup Bearer. 🔭 Whether you're a beginner or an expert, looking at the Night Sky with the naked eye, binoculars or a telescope, check out Hayley's tour of the night sky to find out what you can see this month. #WINS #Astronomy #WhatsInTheNightSky

What are some skywatching highlights in May 2022? May provides some great planet spotting, including a close conjunction of Jupiter and Mars. At mid-month, a total eclipse of the Moon should delight skywatchers across the Americas, Europe, and Africa. And all month long, the Coma star cluster (aka, the Coma Berenices star cluster, or Melotte 111) is a great target for binoculars in the evening. 0:00 Intro 0:11 Planet-spotting opportunities 1:02 Lunar eclipse 2:27 The Coma star cluster 3:33 May Moon phases Additional information about topics covered in this episode of What's Up, along with still images from the video, and the video transcript, are available at https://solarsystem.nasa.gov/skywatching/home.

In May, we are looking away from the crowded, dusty plane of our own galaxy toward a region where the sky is brimming with distant galaxies. Locate Virgo to find a concentration of roughly 2,000 galaxies and search for Coma Berenices to identify many more. Keep watching for space-based views of galaxies like the Sombrero Galaxy, M87, and M64. About this Series “Tonight’s Sky” is a monthly video of constellations you can observe in the night sky.

Marcos Santander, University of Alabama Located under a mile of glacial ice near the South Pole is IceCube, the largest neutrino telescope in the world. IceCube detects high-energy neutrinos, elementary particles that can be produced in distant cosmic objects such as supernova remnants and active galactic nuclei powered by supermassive black holes. Pinpointing the neutrino sources will help answer the century-old question of the origin of cosmic rays, the highest energy particles known in the Universe. In addition, combining observations of neutrinos with those of photons and gravitational waves will enable a new area of multi-messenger astronomical studies. Join Dr. Santander for an overview of the current status of neutrino astronomy, recent highlights from IceCube, and a look at the next-generation neutrino telescopes around the world. Host: Quyen Hart, Space Telescope Science Institute Will be aired live on Tuesday, April 5, 2022 at 4:30 PM EDT (UTC-4) More information: www.stsci.edu/public-lectures

Speaker - Chris Benton Descriptions of most astronomical objects such as planets, stars and galaxies usually include how far away from Earth they are. The quoted distance may involve millions of kilometres, light years or parsecs. Tonight’s talk is Part 1 of 2, discussing the principles and methods used to measure distances across space. First, we cover what light years and parsecs refer to and when astronomers use them, followed by the principles of geometric trigonometry, standard candles, spectral redshifts, standard sirens and standard rulers. We will then review the numerous methods involving those fundamental principles, including how water masers are a new powerful tool, plus what's going on inside Cepheid variable stars that make them so important in this field of astronomy. In May, Part 2 will discuss how scientists use the cosmic distance ladder to calibrate these measurements and maximise precision. We will also discuss the Hubble tension and offer a solution.
