Israeli scientists propose new way to ‘hear’ the universe’s dark matter

Dark matter is a type of matter that does not emit, absorb, or reflect light, making it invisible to telescopes.

 This is an artist's impression of a runaway supermassive black hole that was ejected from its host galaxy as a result of a tussle between it and two other black holes. As the black hole plows through intergalactic space it compresses gas and forms stars (Illustrative).

A rogue star could cast Earth into darkness – and that would be the end of humanity

A new study outlines a rare but chilling scenario: A wandering star from the depths of the galaxy could disrupt the orbits of the planets, fling Earth out of the solar system – and end humanity.

 Are we in a great danger?

Webb telescope documents alien planet's death plunge into a star

The James Webb Space Telescope reveals that planets may spiral into their stars, rather than being swallowed by expanding red giants. This changes our understanding of planetary destruction.

How dust movement is helping us understand magnetic fields and planet formation - study

Planets originate from protoplanetary disks, circulating disks of gas and dust that develop around young stars, a recent study revealed.

 ALMA observations of the protoplanetary disk around HD 142527. The white bars show the directions of the magnetic field revealed by the orientation of the dust grains. The strength of the magnetic field is 0.3 milligauss. For comparison, a typical refrigerator magnet has a magnetic field
