Alien hunting database set up with SETI data

Discovery of pulsars

British astronomer Dame Jocelyn Bell Burnell was the first person to discover a pulsar in 1967 when she saw a radio pulsar.

Since then, other types of pulsars have also been observed that emit X-rays and gamma radiation.

Pulsars are essentially rotating, highly magnetized neutron stars, but when they were first discovered, it was believed that they could come from extraterrestrials.

& # 39; Wow! & # 39; Radio signal

In 1977 an astronomer who was looking for extraterrestrial life in the sky above Ohio saw a powerful radio signal so strong that he got excited & WOW! & # 39; Wrote next to his data.

The 72-second explosion, spotted by Dr. Jerry Ehman through a radio telescope, came from Sagittarius but did not match a celestial body.

Conspiracy theorists have since claimed that the & # 39; Wow! signal & # 39 ;, which was 30 times stronger than background radiation, was a message from intelligent extraterrestrials.

Fossilized martian microbes

In 1996, NASA and the White House made the explosive announcement that the rock contained traces of Marschantsen.

The meteorite, cataloged as Allen Hills (ALH) 84001, deposited 13,000 years ago in the frozen refuse areas of Antarctica and was restored in 1984.

Photographs were released with elongated segmented objects that seemed strikingly lifelike.

However, the excitement did not last long. Other scientists wondered if the meteorite samples were contaminated.

They also argued that heat generated when the stone was blasted into space would have created mineral structures that could be mistaken for microfossils.

Behavior of Tabby's Star in 2005

The star, also known as KIC 8462852, is located at 1,400 light years away and has baffled astonomers since it was discovered in 2015.

It dims at a much faster rate than other stars, which some experts have suggested is a sign of extraterrestrials using the energy of a star.

Recent studies have shown the possibility of an extraterrestrial megastructure & # 39; eliminated and suggest instead that a ring of dust could cause the strange signals.

Exoplanets in the Goldilocks Zone in 2015

In February of this year, astronomers announced that they had seen a galaxy with planets that could sustain life only 39 light years later.

Seven earthy planets were discovered in orbit around the nearby dwarf stars – Trappist-1 & # 39 ;, and they could all have water on their surface, one of the most important components of life.

Three of the planets have such good conditions that scientists say that life has already evolved on them.

Researchers claim that within a decade they will know whether or not there is life on one of the planets, and said & # 39; this is just the beginning & # 39 ;.
