How was 51 Peg b found?
In nearly all cases, exoplanets cannot be seen in the light of their parent stars, and astronomers had to develop clever technologies in order to discover them. As with many extrasolar planets, 51 Pegasi b was found using the radial velocity method.
How was 51 Pegasus found?
The extrasolar planet, 51 Pegasi b, is not visible from Earth, but its presence was deduced from the wobble that its gravity induces in the parent star’s motion in a 4.23-day cycle.

Can we travel to Alpha Centauri?
To get there in anywhere close to a human lifetime, spacecraft will need to travel a substantial fraction of light-speed—10% would get a craft to Alpha Centauri in 44 years. Achieving such phenomenal speeds would require equally eye-watering amounts of energy, even for a relatively lightweight probe.
Is 51 Pegasus in the habitable zone?
A terrestrial planet orbiting 51 Pegasi at around the center of the calculated habitable zone would have an average orbital distance of about 1.6 AU, just beyond the orbit of Mars (towards the Main Asteroid Belt) in the Solar System.
Who is Pegasus father?

Can you touch a star in space?
No. While none exist to date it would be possible for a dead star to have cooled to a safe temperature. However, such objects are inherently supported by degeneracy pressure–they’re very dense.
What is beyond the universe?
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

Will a body decompose in space?
In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.
