How long will the new supernova visible in the night sky last?

It will likely gradually disappear until it is no longer visible in visible light, according to scientists.

Don't worry if you haven't gotten a chance to see the new supernova erupting in the night sky; it should be visible for at least another year. And it won't disappear instantly; rather, researchers anticipate that it will gradually disappear until it is no longer detectable in visible light.

Supernova hunter Koichi Itagaki from Yamagata, Japan initially saw the new supernova on May 19 when he noticed a new bright light in the Pinwheel Galaxy. The next day, the Zwicky Transient Facility (ZTF) in California verified the supernova.

Fortunately for observers and photographers, astronomers anticipate that the explosion will be visible for a while. According to Liverpool John Moores Observatory astronomer Daniel Perley, "We expect the brightness to sort of hold steady for weeks, if not months." It will continue to be brilliant.

Our articles on the finest telescopes and the best telescopes for beginners are excellent places to start if you want to get a glimpse of the supernova SN 2023ixf. Get the appropriate telescope eyepiece, please! Wide-angle eyepieces with reduced magnification should work.

We also have instructions on the finest cameras and lenses for astrophotography if you want to take pictures of the supernova, the Pinwheel Galaxy, or the night sky in general.

The supernova, known as SN 2023ixf, is now one of the biggest and brightest objects witnessed in the last ten years. Even though it is barely out of reach of the naked human eye, it is easily seen using a small telescope or even powerful binoculars. It is situated in the Pinwheel Galaxy, commonly known as Messier 101 (or M101), and has swiftly grown to be a favorite target for both amateur and professional astronomers.

According to Perley, the brilliance will last for "quite some time, perhaps even up to a couple of months." The supernova will then start to fade away. Perley predicted that it will eventually become hardly detectable once more during the following year, two, or three years.

According to Texas A&M Supernova expert Peter Brown, the majority of typical type II supernova, which is the same classification as SN 2023ixf, have a steady brightness for around 100 days before starting to dim.

According to Brown, the latest explosion is a little different from those that came before it. SN 2023ixf has stayed persistently bright, saturating observations with NASA's multiwavelength Swift satellite observatory. Most Type II supernovas taper down rapidly in the ultraviolet spectrum shortly after detection.

In the future, Brown predicted that "this one might fade" since it is unique. But for months, it may continue to be brilliant enough for an amateur astronomer with a nice telescope to view.

Supernovas emit light as a result of interactions between the blown-off star material and the surroundings. In other words, even if it begins to fade, SN 2023ixf could briefly brighten again if it interacts with denser shells or clouds that are encircling the dying star.

The supernova is expected to glow in other sections of the spectrum even after it is no longer visible at visible wavelengths. Large telescopes should be able to view the new find for years, according to Brown, while space telescopes like NASA's Hubble and James Webb may be able to examine the explosion for decades.

However, you shouldn't wait another year before taking your telescope outside. There is no assurance that the supernova will last, despite scientists' expectations.

It still could shock us, Perley remarked. "We are unsure for sure."
