A treasure hunt for the origin of gamma rays with very high energy

What does the VHE sky look like? These authors are looking for VHE gamma rays from blazers collected by several catalogs, including 4FGL-DR3 from Fermi-LAZY called (which can be seen in Figure 2), Roma-BZCat, as well as other catalogs of blazers. The extragalactic sky is dominated by blazers, which can be seen in the blue …

The cell’s power package has a more complicated origin than we thought

For billions years after the origin of lifethe only living beings on earth were small, primitive cells similar to those of today bacterium. But then, more than 1.5 billion years ago, something remarkable happened: one of these primitive cells, belonging to a group known as archaeaswallowed another – a bacterium. Instead of being digested, the …

New molecules found on a nearby asteroid can reveal the origin of life

In 2014, the Japan Aerospace Exploration Agency (JAXA) sent his Hayabusa2 spaceships to meet with 162173 Ryugu, a Near-Earth Asteroid (NEA) that periodically passes near Earth. In 2018, this test-return mission reached Ryugu and spent the next year and a half studying its surface and taking samples from its surface and below the surface. In …
