A new study introduces CIGaRS, a novel approach to derive highly precise estimates of cosmic distances and robust cosmological measurements. This method uses artificial intelligence and neural networks to disentangle the intrinsic effects on supernovae light from environmental factors.
A team of astronomers found that fast X-ray transients are associated with the explosive death of massive stars, including supernovae. The International Gemini Observatory and SOAR telescope observed the event, providing insight into its mechanisms.
Researchers have found visual evidence of a double detonation process in the remains of a star that exploded twice, providing new insights into the mechanism behind Type Ia supernovae. This discovery confirms a long-standing hypothesis and offers a tangible explanation for these cosmic events.
A new study suggests that the Hypatia Stone, discovered in Egypt, may be the first tangible evidence on Earth of a supernova type Ia explosion. The stone's unique chemistry and elemental composition contradict conventional views of solar system formation, potentially revealing a long-hidden secret about our cosmic neighborhood.
Researchers used computer modeling to simulate the long-term evolution of a hypothesized type of supernova, known as D6. The study found that remnants of type Ia explosions are not necessarily symmetric, offering new insights into supernova physics. This finding has significant implications for using Ia supernovae as cosmic yardsticks.
Astronomers have witnessed a cosmic explosion about 200 times more powerful than a typical supernova, shedding light on the mysterious 'superluminous' explosions. The record-breaking blast, ASASSN-15lh, shone with 570 billion times the brightness of the Sun and is thought to be an outstanding example of a rare stellar scenario.
