Unveiling Cosmic Secrets: Hubble’s Astonishing Glimpse at Supernova SN 2022AAJN
The Hubble Space Telescope’s ability to capture such detailed images of SN 2022AAJN represents a milestone in astronomical exploration. With its unprecedented image quality, Hubble provides astronomers with the means to explore cosmic events in greater depth and detail. This capability marks the start of a new era in astronomical science, where advanced imaging combines with cutting-edge data analysis tools, like machine learning, to accelerate discoveries and deepening our understanding of cosmic events such as supernovae and dark energy.

Physicists Are Using Time Itself to Crack the Dark Matter Puzzle
Using atomic clocks and ultra-stable lasers, they tracked subtle changes in time to detect hidden dark matter waves. By measuring precision shifts across vast distances, the study opens doors to new discoveries in fundamental physics.
Unveiling Dark Matter with a Bold New Approach
A team of international researchers has developed a novel method to investigate dark matter, the mysterious substance believed to hold galaxies together.
Dark matter dominating halos of supermassive black holes 13 billion light-years away
Kavli IPMU Professor John Silverman said, “Vera Rubin provided the first evidence for dark matter using the rotation curves of nearby local galaxies. We’re using the same technique but now in the early Universe.”
Blue-shifted (towards researchers) and redshifted (away) gas show velocity changes in the galaxy. Unlike past studies, which showed less dark matter in the galaxy’s outskirts, their data shows a flat rotation curve, indicating that more dark matter is needed for high velocities.
These findings shed light on the relationship between dark matter and supermassive black holes, helping us understand galaxy evolution from the early Universe to today.

Supermassive black hole displays ‘unprecedented’ X-ray outbursts
An international team of researchers has detected a series of significant X-ray oscillations near the innermost orbit of a supermassive black hole – an unprecedented discovery that could indicate the presence of a nearby stellar-mass orbiter such as a white dwarf.
Optical outburst
The Massachusetts Institute of Technology (MIT)-led team began studying the extreme supermassive black hole 1ES 1927+654 – located around 270 million light years away and about a million times more massive than the Sun – in 2018, when it brightened by a factor of around 100 at optical wavelengths. Shortly after this optical outburst, X-ray monitoring revealed a period of dramatic variability as X-rays dropped rapidly – at first becoming undetectable for about a month, before returning with a vengeance and transforming into the brightest supermassive black hole in the X-ray sky.
