Hubble Telescope views a galactic supernova site.

 



In this image the spotlight falls on the diminutive galaxy UGC 5189A, positioned approximately 150 million light-years distant within the Leo constellation. The NASA/ESA Hubble Space Telescope turned its gaze toward this cosmic neighbor to scrutinize the aftermath of a spectacular supernova, specifically the explosive event known as SN 2010jl, which unfolded in 2010.What sets this supernova apart is its extraordinary luminosity, outshining our Sun by a staggering 2.5 billion times in visible energy over a remarkable three-year span. The sheer brilliance of SN 2010jl stands as a celestial spectacle, offering astronomers valuable insights into the dynamics of these cosmic explosions.


The allure of studying the aftermath of supernovae extends beyond their visible lifespans, offering a window into the intriguing realms where these cosmic explosions transpired. Even as their luminosity wanes, delving into the environments that hosted these supernovae becomes a key avenue for astronomers. Such investigations yield valuable insights, enhancing comprehension of the diverse triggers behind supernova occurrences. Supernova's studies play a pivotal role in unraveling the immediate consequences of these events – from their profound impact on surrounding gas and dust to the enduring stellar remnants they leave in their wake. In essence, each exploration into these cosmic aftermaths contributes to a deeper understanding of the intricate tapestry of celestial phenomena.


The image presented here stems from data amassed in three of Hubble's most recent studies dedicated to unraveling the mysteries of UGC 5189A.These comprehensive investigations not only delve galaxy but also cast their lens on other neighboring galaxies that have played host to recent supernovae. In astronomical terms, the term "relatively nearby" takes on cosmic proportions, indicating galaxies positioned approximately 100 million light-years away. Through this ongoing scrutiny, astronomers glean a more nuanced understanding of the dynamic processes shaping these distant cosmic landscapes.

NASA/ESA Hubble Telescope Captures Image of Supernova to Aid Distance Measurements.

  The Hubble Space Telescope has recently captured a striking image of a supernova-hosting galaxy, located approximately 600 million light-years away in the constellation Gemini. This image, taken about two months after the discovery of supernova SN 2022aajn, reveals a bright blue dot at the center, signifying the explosive event. Although SN 2022aajn was first announced in November 2022, it has not yet been the subject of extensive research. However, Hubble's interest in this particular supernova lies in its classification as a Type Ia supernova, a type that is key to measuring cosmic distances. Type Ia supernovae occur when a star's core collapses, and they are particularly useful for astronomers because they have a predictable intrinsic brightness. No matter how far away a Type Ia supernova is, it emits the same amount of light. By comparing its observed brightness to this known luminosity, astronomers can calculate how far away the supernova — and its host galaxy — are from...

Solar Storm Shocker: Earth Gets a Cosmic Makeover with Two New Radiation Belts!

  The May 2024 solar storm formed two new radiation belts between the Van Allen Belts, with one containing protons, creating a unique composition never observed before. Picture this: May 2024, the Sun throws a massive tantrum, sending a solar storm hurtling toward Earth. The result? Stunning auroras light up the skies, GPS systems go haywire, and—wait for it—Earth gets two brand-new *temporary* radiation belts! That’s right, our planet just got a cosmic upgrade, thanks to the largest solar storm in two decades. And no, this isn’t a sci-fi movie plot—it’s real science, folks!   Thanks to NASA’s Colorado Inner Radiation Belt Experiment (CIRBE) satellite, scientists discovered these new belts, which are like Earth’s Van Allen Belts’ quirky cousins. Published on February 6, 2025, in the *Journal of Geophysical Research: Space Physics*, this discovery is a game-changer for space research, especially for protecting satellites and astronauts from solar storm shenanigans. ...

Tropical Cyclone Sean Hits Western Australia, Breaking Rainfall Records and Causing Damage.

  On January 17, 2025, a tropical low formed over the Indian Ocean off Western Australia. By January 19, the system had intensified into Tropical Cyclone Sean, marking the second tropical cyclone of Australia’s 2024–2025 season. NASA’s Terra satellite, using the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument, captured a detailed image of the storm at around 10 a.m. local time (02:00 Universal Time) on January 20, 2025. Later that same day, Cyclone Sean reached its peak strength as a Category 4 storm. Despite staying offshore and not making landfall, Cyclone Sean still brought significant impacts to the Pilbara coast. The Australian Bureau of Meteorology (BoM) reported that Karratha, a coastal city in the region, received a staggering 274.4 millimeters (10.8 inches) of rain in just 24 hours, setting a new single-day rainfall record for the city. The powerful storm caused widespread flooding, with roads submerged, homes affected, and power infrastructure damaged. Se...
