It was “a really exciting couple of hours” to make sure what they saw “was real,” Kostov said.

“Once we were pretty confident that they were mostly real, we reached out to the rest of the team,” Kostov said. Other team members found more transits of the planet, giving them more evidence.

Because the planet is so big, NASA scientists believe it is made of gas, like Saturn or Jupiter. Even if it had been rocky, like Earth, the planet seems to be too close to one of the stars to be able to support life.

What Cukier had found was evidence of changes in the light of the two stars, called binary stars. The way scientists “see” such a distant planet is by changes in light. If a planet is moving between the telescope and the star it orbits, it produces an effect similar to an eclipse that we see here on Earth.

In other words, the planet blocks some of the sun’s light from the telescope. In graphs and other data, this shows up as a dip -- a line that moves down and then up again.

Later that day, Cukier met with his boss, Veselin Kostov, to go over his find.

Such blood tests, called liquid biopsies, are already used in patients with cancer to establish treatment and check to see if cancerous growths come back.

Several drug companies are pushing for the blood test as part of regular health screening to find cancerous growths, or tumors, in certain parts of the body.

Grail, a California-based company, is far ahead of others with 2,000 doctors willing to prescribe the $949 test. Most insurance plans do not cover the cost.

The Food and Drug Administration demands an extensive study of a drug or vaccine before approval. A review by the agency is not required for this kind of blood test. But Grail plans to seek approval from the FDA while it is marketing the tests.

The 63-year-old Lopez-Alegria was described as the mission commander. He was joined by the mission pilot, Larry Conner, a 72-year-old businessman and private pilot from Ohio. The other members were 64-year-old Israeli man Eytan Stibbe, a fighter pilot and 52-year-old Mark Pathy, a Canadian businessman. Stibbe and Pathy served as mission specialists.

After being helped out of the capsule, the crew members were picked up by a recovery ship and given a quick health examine. The team was then flown to NASA in Florida for more detailed medical check-ups.

"Everybody looks great and is doing reasonably well," Axiom operations director Derek Hassmann told reporters. He described the astronauts as being "in great spirits."

The first private astronaut crew to visit the International Space Station (ISS) has returned safely to Earth.

The team flew to the ISS and back on the spaceship Crew Dragon. The SpaceX company vehicle landed as planned in the Atlantic Ocean off the coast of Florida on Monday. SpaceX also provided the Falcon 9 rocket that carried the team to orbit.

The return to Earth marked the end of a two-week science mission aboard the ISS. The flight was the first to be organized and operated by a private company involving a completely commercial astronaut crew.

“Welcome back to planet Earth," SpaceX Mission Control said in a radio message to the crew. “We hope you enjoyed the extra few days in space.”
