Japanese astronomers have captured images of an astonishing 1800 supernovae. 58 of these supernovae are the scientifically-important Type 1a supernovae located 8 billion light years away and are known as ‘standard candles’ in astronomy.
Many supernovae show a gradual increase in the light they put out. But for ASASSN-18bt, you could clearly see there's something unusual and exciting happening in the early times - an unexpected additional emission.
On August 22, 2016, astronomers spotted a superluminous supernova whose light traveled over 10 billion years to reach us.
Contrary to what was expected, a team of astronomers has discovered that kilonova event has been brightening ever since it first appeared.
With globe-spanning collaboration that enables to alert various telescopes to train their sights on the event, we are getting closer and closer to understanding how massive stars end their life and what leads up to the final explosion.
Mark your calendars: In 2022, a rare "red nova" will appear in the sky, according to an unprecedented and ultra-precise stellar prediction.
Discovery of a time-resolved supernova signal in Earth's microfossils. According to the researcher's analyses, our solar system spent one million years to transit trough the remnants of a supernova.
This animation is based on photometric observations made by NASA’s Kepler space telescope. By closely monitoring the star KSN 2011d, located 1.2 billion light-years away, Kepler caught the onset of the early flash and subsequent explosion.
In January 2002, astronomers discovered a massive explosion coming from V838 Monocerotis. They initially thought they were witnessing a supernova, but after the initial flash of light began to dim (as expected), it began to brighten again in infrared wavelengths at the beginning of March. After that brightening faded, another one happened in April.
