The pursuit of understanding dark matter, which comprises 85 percent of the universe’s mass, could take a significant leap forward with a nearby supernova. Researchers at the University of California, Berkeley, led by Associate Professor of Physics Benjamin Safdi, have theorised that the elusive particle known as the axion might be detected within moments of […]
Hey all This may be obscure but i never thought to reference this on reddit. Is there a way to track the night sky going back years? In mid October to mid November sometime in 2014, i was hanging out of my window and witnessed what looked to be a supernova. It was still, white, […]
Astronomers have crafted a detailed three-dimensional map of the Local Hot Bubble (LHB), a vast, low-density region surrounding our solar system. This bubble, filled with hot, X-ray-emitting gas, has been a subject of study since the 1970s, and recent data from the eROSITA All-Sky Survey has provided new insights into its structure and history. The […]
A supernova, an explosive end to a star’s life cycle, has the potential to impact planets in its proximity, including Earth. If a star were to go supernova within close range of our planet, the radiation it emits could lead to catastrophic consequences for life as we know it. However, any significant threat would depend […]
NGC 1672, as seen by the Hubble Space Telescope The NASA/ESA Hubble Space Telescope continues to churn out fantastic space images. The latest captured by the 34-year-old telescope shows barred spiral galaxy NGC 1672 in all its luminous glory. NGC 1672 is about 49 million light-years from Earth in the constellation Dorado. Like other spiral […]
In AD 1181, astronomers in China and Japan recorded a new star in the sky, a rare supernova explosion. The remains of that supernova, called SN 1181, are depicted here in this artist’s animation, which flies around the remnant as it appears today. W. M. Keck Observatory / Adam Makarenko Astronomers have, for the first […]
Could Betelgeuse, the bright star in the constellation Orion, actually have a companion star? This question is gaining attention after recent research suggested that a partner star might explain Betelgeuse’s unusual brightness changes. Known as a red supergiant, Betelgeuse has been observed dimming in a way that has sparked discussions about when it might go […]
When a star goes supernova in a giant explosion, it can clear away matter in nearby star systems muratart/Shutterstock The blast from a supernova should be enough to clear almost all the dust from the solar system, and this may have last happened 3 million years ago. But like the dust on furniture, these fine […]
This image, released on Feb. 24, 2017, shows Supernova 1987a (center) surrounded by dramatic red clouds of gas and dust within the Large Magellanic Cloud. This supernova, first discovered on Feb. 23, 1987, blazed with the power of 100 million Suns. Since that first sighting, SN 1987A has continued to fascinate astronomers with its spectacular […]
The massive galaxy cluster PLCK G165.7+67.0, also known as G165, is shown at left. Its gravity, like a gravitational lens, magnifies and distorts the images of background galaxies. In one of these, shown in the inset at right, are three bright images of the same supernova, dubbed H0pe (labeled with white dashed circles). NASA, ESA, […]
