Supernova

Researchers have confirmed the existence of a neutron star at the center of Supernova 1987A, using the James Webb Space Telescope. This discovery resolves a long-standing mystery and contributes significantly to our understanding of supernovae and their role in the cosmos. Credit: HST, JWST/NIRSpec, J.

Nearly forty years ago residents of Earth were treated to a rare cosmic sight: an exploding star in our sky that was visible to the naked eye. Called Supernova 1987A (SN 1987A), it was the closest such event of the past four centuries. Ever since astronomers have sought to observe the stellar remnant that they have known must lurk near the supernova’s center, shrouded within an expanding nebula of radioactive ash and incandescent gas. Now, thanks to the power of the James Webb Space Telescope (JWST), a team of scientists…

A recent SETI (Search for Extraterrestrial Intelligence) effort focused on a famous supernova from 1987, working under the premise that aliens might use such events to draw attention to themselves with synchronized beacons. Although this hunt came up short, it lays the groundwork for future searches using the same innovative strategy.Nvidia’s Almost Worth 2 Trillion. Is It a Bubble, or Is It Just Getting Started?This principle, called the SETI Ellipsoid strategy, offers a potential solution to a challenging problem: How…

Following successful DC fast charger launches in Europe, Wallbox has begun production on its third-generation EV charger, the Supernova 180. This UL-certified DC fast charger was explicitly designed for the North American market and can add 100 miles of EV range in ten minutes. Wallbox ($WBX) is a global charging specialist founded in 2015 that develops, manufactures, and sells charger equipment and energy management solutions for residential and public use in over 100 countries. Although the…

Astronomers have discovered that Type Ia supernovae, through interactions with surrounding gas, are a new source of cosmic dust, challenging previous beliefs that dust formation was exclusive to core-collapse supernovae. This discovery expands our understanding of dust formation in elliptical galaxies, potentially revising our views on the cosmic cycle of matter.

Recording Academy CEO Harvey Mason Jr. took to the 2024 Grammys stage to pay tribute to the victims of the Supernova music festival massacre that launched the Israel–Hamas war on Oct. 7, 2023. “Tonight, we celebrate the world of music,” he said. “Every one of us, on matter where we’re from, is united by the shared experience of music. It brings us together like nothing else can and that’s why music must always be our safe space. When that’s violated, it strikes at the very core of who we are.”…

The universe is misbehaving.Upon its birth in the big bang, nearly 14 billion years ago, the cosmos began expanding. And for most of the 20th century, scientists assumed gravity would gradually slow down that expansion, with all the universe’s matter acting as drag.But observations in the late 1990s showed that’s far from the case. Careful, high-precision estimates of cosmic distances using a special class of exploding stars called type Ia supernovae revealed that, against all expectations, the universe’s expansion is…

This Hubble Space Telescope image features the spiral galaxy IC 438, located 130 million light-years away in the constellation Lepus. Surrounded by constellations such as Canis Major, Orion, and Canis Minor, Lepus is part of the 88 constellations officially recognized by the IAU, which divide the night sky into distinct regions for easier identification of celestial objects.

FilippenkoHubble’s observations of the galaxy UGC 5189A and the exceptionally bright supernova SN 2010jl provide critical insights into the nature and aftermath of supernovae.This image from the Hubble Space Telescope features a relatively small galaxy known as UGC 5189A, which is located about 150 million light-years away in…

Astronomers discovered enormous radio wave circles in 2019, named ORCs. Research led by Professor Alison Coil indicates these are caused by galactic winds from starburst galaxies, providing new insights into galactic evolution and phenomena. Credit: SciTechDaily.comOutflowing galactic winds from exploding stars may explain the enormous rings.It’s not every day astronomers say, “What is that?” After all, most observed astronomical phenomena are known: stars, planets, black holes, and galaxies. But in 2019 the newly…
