Hubble Space Telescope–“Witnessing a Gargantuan Star’s Utter Destruction” 

 

blue variable star AG Carinae

 

“I like studying these kinds of stars because I am fascinated by their instability. They are doing something weird,” said Kerstin Weis, a luminous blue variable expert at Ruhr University in Bochum, Germany. The Hubble Space Telescope recently captured the nebulosity surrounding the rare luminous blue variable star AG Carinae pictured above. Less than 50 luminous blue variables are known to exist among our local group of neighboring galaxies.

Titanic Explosion in Andromeda –A Prelude?

 

Andromeda Galaxy

 

So far, we have had only close calls from gamma ray explosions so large, scientists have suggested, that if they occurred within our solar neighborhood (less than 1,000 light years) they could potentially trigger mass extinctions on Earth.

“New Cosmic Beast”–A Mysterious Cataclysm Observed

 

The Camel

 

“Somewhere,” said Carl Sagan, “something incredible is waiting to be known” –“I’ve never seen anything like this before in the local universe,” said Stephen Smartt, an astrophysicist at Queen’s University Belfast and a lead scientist for the Hawaii-based ATLAS survey, about “something incredible” –a mysterious cataclysm in a neighboring galaxy that rocked the world’s astronomy community with its discovery on June 16, 2018.

Pulsing Supergiant Betelgeuse Discovered Closer to Earth –“May Someday Collapse into a Black hole or Neutron Star”

Betelgeuse-

 

Seething supergiant Betelgeuse –a star so huge it could someday collapse into a black hole or neutron star, which would make it the closest black hole to Earth some 725 light-years distant– has displayed unprecedentedly large drop in its brightness in early 2020, prompting speculation that the pulsing may be a dire prelude. A new study by an international team of scientists concluded that the star is in the early core helium-burning phase (more than 100,000 years before a supernova event) and has smaller mass and radius–and is closer to Earth–than previously thought. If the bright-red object  replaced the Sun at the center of our solar system, its outer surface would extend past the orbit of Jupiter.

“Ghostly Messengers” –Massive Underground Instrument Reveals ‘Final Secret’ of Our Sun

Borexino Sphere

 

When we consider the origins of life in our Solar System, a remarkable discovery has to be taken into account –the Solar System is substantially over-abundant in metals compared with average interstellar abundances at the time of its formation 4.6 billion years ago. These solar abundances are similar to present interstellar abundances, an anomaly that remains a mystery. One possibility scientists suggest is that the Sun formed much closer to the galactic center than its current position, which may have resulted in a plentiful supply of raw materials in the solar nebula from which to form the Earth and its biosphere.

“Our Original Sun was a Supernova” –Has the Phenomenon Effected Earth’s Evolution and Climate?

Vela Supernova

 

“Although Earth was originally created from the Sun (as part of the ecliptic plane of debris and dust that circulated around the Sun 4.5 billion years ago), our Sun is barely hot enough to fuse hydrogen to helium, observed physicist Michio Kaku in Parallel Worlds: A Journey through Creation, Higher Dimensions, and the Future of the Cosmos. “This means that our true “mother” sun was actually an unnamed star or collection of stars that died billions of years ago in a supernova, which then seeded nearby nebulae with the higher elements beyond iron that make up our body. Literally, our bodies are made of stardust, from stars that died billions of years ago.”
