According to the most widely accepted scientific theory, our Solar System formed from a nebula of dust and gas roughly 4.56 billion years ago (aka. Nebula Theory). It began when the nebula experienced gravitational collapse at the center, fusing material under tremendous pressure to create the Sun. Over time, the remaining material fell into an extended disk around the Sun, gradually accreting to form planetesimals that grew larger with time. These planetesimals eventually experienced hydrostatic equilibrium, collapsing into spherical bodies to create Earth and its companions.

Dark Matter Could Map the Universe's Early Magnetic Fields
We think of magnetic fields as a part of planets and stars. The Earth and Sun have relatively strong magnetic fields, as do more exotic objects such as neutron stars and the accretion disks of black holes. But magnetic field lines also run throughout galaxies, and even between the vast voids of intergalactic space. Magnetic fields are quite literally everywhere, and we aren’t entirely sure why. One idea is that faint magnetic fields formed during the earliest moments of the Universe. If that’s the case, we might be able to prove it through the distribution of dark matter.
This Week's Sky at a Glance, January 12 – 21

A Self-Eating Engine Could Make Rockets More Efficient
There can’t be many ideas that beat the crazy yet ingenious idea of a rocket engine that actually uses part of the fuselage for fuel! Typically a rocket will utilise multiple stages so that excess weight can be jetisoned allowing the rocket to be as efficient as possible. Now a team in Scotland is working on a rocket engine that actually consumes part of its body to use as fuel, reducing weight and providing even more thrust so that greater payloads can be used.

There are Mysteries at Venus. It’s Time for an Astrobiology Mission
When scientists detected phosphine in Venus’ atmosphere in 2020, it triggered renewed, animated discussions about Venus and its potential habitability. It would be weird if the detection didn’t generate interest since phosphine is a potential biomarker. So people were understandably curious. Unfortunately, further study couldn’t confirm its presence.
