What is he intergalactic star database?

Space is not empty. It is not a complete vacuum. Even between stars and galaxies there exists gasses and dust. In intergalactic space the material will be very diffuse. Also,...

A planet can get ejected from a solar system by the gravitational pull of its sun, another planet or another star passing through its solar system. There are problems with...

Intergalactic space (IGS) is near-absolute vacuum but not vacuum. The very hot hydrogen plasma in the void (one highly compressed and confined atom in a cubic meter) is highly conductive...

Gravity is a force that reduces its strength inverse square relation with distance..

In the core of a main sequence Star temperature and pressure is high enough to undergo hydrogen fusion but it is still not enough to fuse the helium that is...

The core of massive stars has more gravitational pressure on its core, resulting in a faster bombardment of atoms (fusion). This forces the massive star to run out of its...

A parsec, about 3.26 light-years, is the distance where a star appears to shift by one second of arc as moves from one point in its orbit to the opposite...

Intergalactic travel maybe possible within the 21st century. Astrophysicists have already given ideas, such as the space warping spacecraft (which could allow it to travel faster than light without breaking...

The relationship between a star's distance and its parallax angle is given by $d = 1/p$, where the distance $d$ is measured in parsecs (equal to $3.26$ light years) and...

Stars are formed when a cloud of gasses, mainly hydrogen, collapse due to gravity. As more and more gas accumulates the temperature rises. The temperature creates an outward thermal pressure....
