An Alternate Universe: Our Cosmos May Have Been Spawned by a Hypermassive Black Hole

An Alternate Universe: Our Cosmos May Have Been Spawned by a Hypermassive Black Hole

The most accepted theory of the origin of the universe is still the Big Bang. The theory proposes the universe started from a small singularity (the gravitational kind), then began to expand over the succeeding 13.8 billion years. Although this expansion has its own issues, a bigger question remains: what preceded the Big Bang?

Scientist find treasure trove of giant black hole pairs

For decades, astronomers have known that Supermassive Black Holes (SMBHs) reside at the center of most massive galaxies. These black holes, which range from being hundreds of thousands to billions of Solar masses, exert a powerful influence on surrounding matter and are believed to be the cause of Active Galactic Nuclei (AGN). For as long as astronomers have known about them, they have sought to understand how SMBHs form and evolve.

Astronomers find the missing normal matter in the universe, still looking for dark matter, though

Astronomers find the missing normal matter in the universe, still looking for dark matter, though

For decades, the predominant cosmological model used by scientists has been based on the theory that in addition to baryonic matter – aka. “normal” or “luminous” matter, which we can see – the Universe also contains a substantial amount of invisible mass. This “Dark Matter” accounts for roughly 26.8% of the mass of the Universe, whereas normal matter accounts for just 4.9%.

Debris disk around stars could point the way to giant exoplanets

Debris disk around stars could point the way to giant exoplanets

According to current estimates, there could be as many as 100 billion planets in the Milky Way Galaxy alone. Unfortunately, finding evidence of these planets is tough, time-consuming work. For the most part, astronomers are forced to rely on indirect methods that measure dips in a star’s brightness (the Transit Method) of Doppler measurements of the star’s own motion (the Radial Velocity Method).

Scientists Have Completed the First-Ever “Atlas of Life”

Scientists Have Completed the First-Ever “Atlas of Life”

Climate change, deforestation, and other threats put a huge portion of wildlife at risk. An international team of scientists have finished a new atlas map that highlights the location of 10,000 reptile species, and shows areas in need of better protection.

This meteorite came from a volcano on Mars

This meteorite came from a volcano on Mars

Today, it is well understood that Mars is a cold, dry, and geologically dead planet. However, billions of years ago when it was still young, the planet boasted a denser atmosphere and had liquid water on its surface. Millions of years ago, it also experienced a significant amount of volcanic activity, which resulted in the formation of it’s massive features – like Olympus Mons, the largest volcano in the Solar System.

How we found our lost Mars lander after a decade of searching – and what’s next

How we found our lost Mars lander after a decade of searching – and what’s next

The last picture taken of the Mars lander Beagle 2 showed it being successfully ejected from Mars Express on Christmas Day in 2003. But sadly, we never got a signal back from the lander and have ever since tried to work out what happened, and where it is. Eventually we made a breakthrough – and our findings have now been published in Royal Society Open Science.

Scientists Have Proposed Building an Earth-Sized Shield to Protect Our Planet

Scientists Have Proposed Building an Earth-Sized Shield to Protect Our Planet

A massive solar storm called a coronal mass ejection could knock out Earth's electrical grid and communication systems, causing trillions of dollars in damage. With such an event likely in the future, two astrophysicists have proposed the construction of a shield to protect Earth.

Scientists Just Found Half of the Missing Matter in Our Universe

Scientists Just Found Half of the Missing Matter in Our Universe

Two teams of astronomers have found a way to observe the presence of the missing matter connecting the galaxies in the universe. This discovery can improve our understanding of how galaxies were formed in the years following the Big Bang.
