    Explanation:
    A long time ago, in a distant galaxy, a massive star was destroyed in a supernova explosion. The light of this event travelled for tens of millions of years and reached Earth last week as Supernova 2026kid. The featured video shows a time-lapse over three nights of the host galaxy NGC 5907, an edge-on spiral also known as the Splinter or Knife Edge Galaxy, as the supernova appears and becomes brighter. (The occasional streaks are satellites in Earth orbit.) At its brightest, a supernova can outshine the sum of all other stars in its galaxy. Supernova 2026kid appears relatively dim, probably because we are seeing it through the edge-on disk of the galaxy. Such explosions typically happen about once per century in galaxies similar to the Milky Way, and their light can take months to fade away. The brightest supernova in recorded history was SN 1006; it is reported to have been brighter than Venus, and even visible in the sky during daytime.

  2. Fu la supernova più brillante mai documentata nella storia, un’esplosione stellare di potenza estrema che trasformò temporaneamente l’aspetto del cielo e lasciò tracce durature sia nella memoria umana sia nella materia dello spazio.

  4. A strange ‘chirp’ in a brilliant stellar blast points to a #magnetar
    About a billion light-years away, an extraordinary stellar explosion lit up in the night sky. The blast, detected December 12, 2024, was some 30 times the brightness of a typical #supernova, putting it in a rare group of superluminous #supernovas. Now, #astronomers believe they know what made the explosion so bright — an extreme type of star called a magnetar.

If that what it means, then it’s not going to be Kwangya style. Is Supernova considered to be Kwangya style?

  11. A #Supernova #Remnant is the structure resulting from the explosion of a star, consisting of ejected material expanding outward at high speeds into the surrounding interstellar medium.

    These remnants are often characterized by vibrant, glowing shells of gas and dust.

  13. Rubin Observatory spustil alertový systém
    📡 Historický milník: Observatoř Vera C. Rubin v Chile spustila 24. 2. real-time alertový systém. První noc — 800 000 alertů: supernovy, proměnné hvězdy, aktivní jádra galaxií, asteroidy.
    Cíl: až 7 milionů alertů/noc. Změny hlášeny do 2 minut od snímku. Největší digitální kamera (3 200 Mpx) začíná plnit účel. Letos startuje desetiletý průzkum LSST.
