This Supernova Progenitor Hid Behind a Surprisingly Thick Veil of Carbon Dust

For the first time, astronomers have used images from the NASA/ESA/CSA James Webb Space Telescope to identify a supernova progenitor that could not be seen by any other telescope: a red supergiant that was located in a nearby galaxy. The supergiant’s surroundings were surprisingly dusty - dusty enough to render it invisible to the NASA/ESA Hubble Space Telescope. from Universe Today https://ift.tt/9uXhs1n via IFTTT

Super-Jupiters Challenge Planet Size Limits

Our solar system is home to a wide diversity of planetary bodies, boasting eight planets, five officially recognized dwarf planets, and almost 1,000 confirmed moons. The eight planets consist of the four rocky (terrestrial) planets of the inner solar system and the four gas giant planets of the outer solar system. The largest planet in our solar system is Jupiter, measuring a radius and mass of 11 and 318 times of Earth, respectively. However, the discovery of exoplanets quickly altered our understanding of planetary sizes, as several have been discovered to have masses and radii several times that of Jupiter. So, how big can planet get, and are there limits to their sizes? from Universe Today https://ift.tt/3qomFig via IFTTT

Sampling Earthly Geysers For Insights Into The Icy Ocean Moons

One way of studying and understanding distant, hard-to-reach locations elsewhere in the Solar System is to find analogues of them here on Earth. For example, deserts and lava fields are often used to understand aspects of the Martian surface. In new research, scientists collected samples from natural geysers in the Utah desert to try to understand the Solar System's icy ocean moons. from Universe Today https://ift.tt/pgE7kHN via IFTTT

Exploring Alien Atmospheres with New Theory

Searching for life beyond Earth has rapidly advanced in recent years. However, directly imaging an exoplanet and all their incredible features remain elusive given the literal astronomical distances from Earth. Therefore, astronomers have settled by exploring exoplanet atmospheres for signatures of life, also called biosignatures. This is currently conducted by analyzing the starlight that passes through an exoplanet’s atmosphere, known as spectroscopy, as it passes in front of its star, also called a transit. But improvements continue to be made to better explore exoplanet atmospheres, specifically cleaning up messy data. from Universe Today https://ift.tt/iz6st1S via IFTTT

Could it be We've Recieved Alien Signals in the Past and Didn't Notice? Not Bloody Likely, According to New Study

For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically expect to detect today? from Universe Today https://ift.tt/Le7KAzR via IFTTT
