A mega comet has entered our solar system. Named 2014 UN271, the object will approach the Sun and reach Saturn’s orbit in 2031.
It is estimated to be 100 to 370 km wide, and this object is larger than the typical feature of a comet, making it more likely to be a dwarf planet.
This illustration shows the distant Comet Bernardinelli-Bernstein as it might look in the outer Solar System. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It is the most distant comet to be discovered on its incoming path.
In a nutshell, black holes are objects that cannot be penetrated by light due to the force of gravity.For gravity to be so great that even light cannot escape, it is not enough to add the weight or mass of...
The intermittent long eclipses observed while observing the star J1407 astonished astronomers that at first it was thought to be a planet, but when closely observed, the data obtained suggest that it was orbiting like Saturn. This is the first...
