Astronomers have found over 5,000 confirmed exoplanets to this point, together with many different candidates awaiting affirmation. Scientists anticipate hundreds extra discoveries within the coming months and years. And now, NASA needs you to join in the search! You should utilize your personal telescope and even your smartphone to assist research and detect exoplanets. The mission, referred to as Exoplanet Watch, is a novel manner for the general public to assist astronomers research and discover distant new worlds.

The Exoplanet Watch mission
Exoplanet Watch is a citizen science mission managed by NASA’s Jet Propulsion Laboratory (JPL), a part of NASA’s Universe of Learning program. It started in 2018, however now it’s even higher and extra simply accessible to the general public at massive. Anybody can participate. As Rob Zellem, creator of Exoplanet Watch and an astrophysicist at Jet Propulsion Laboratory, said:
With Exoplanet Watch you possibly can learn to observe exoplanets and do knowledge evaluation utilizing software program that precise NASA scientists use. We’re excited to point out extra individuals how exoplanet science is basically performed.
Individuals in Exoplanet Watch use the EXOplanet Transit Interpretation Code (EXOTIC) software program. The mission web site contains useful tutorials and guides to get you began.
Utilizing your personal telescope to assist NASA research exoplanets
There are two methods you possibly can help with Exoplanet Watch. The primary entails utilizing your personal telescope in case you have one. There isn’t a dimension restrict to what telescope you should use, though a bigger telescope can see extra targets. Even a small six-inch (15-cm) telescope might detect planet transits round some close by stars. A transit is when a planet passes in entrance of its star, as seen from Earth. This causes a small however measurable non permanent decline in brightness of the star.
An ideal facet of Exoplanet Watch is that it makes use of observations of the identical targets from a number of individuals. This mixture of knowledge helps to acquire extra correct measurements. It is usually supreme for exoplanets with lengthy transit durations. That’s, if the transit lasts longer than the time the star is seen to a single observer. Now, observers from world wide might help observe the transit on the similar time. For instance, 20 contributors watched the transit of the exoplanet HD 80606 b.
NASA’s Webb telescope may even observe that exoplanet later this 12 months. However now, Webb may have about two additional hours of observing time, because of the observations that the Exoplanet Watch members already did. The refining of the transit measurements that Exoplanet Watch already accomplished now frees up further time for Webb to look at different targets.
No telescope? Use your smartphone!
Even if you happen to don’t have a telescope, you possibly can nonetheless participate in Exoplanet Watch. You should utilize your smartphone to obtain the information – 10 years’ price to this point – and assist search for exoplanet transits. Whereas the information can reveal new planets, Exoplanet Watch members largely take a look at knowledge from planets already found. This helps astronomers be taught extra about these planets’ orbits.
As well as, Exoplanet Watch contributors will search for some other variations within the brightness of the celebs. Flares and star spots (solar flares and sunspots on our personal solar) could cause such variations. In addition they have an effect on the observations of any planets orbiting the celebs. For instance, they will make the planet appear smaller or bigger than it truly is. Variations like these, subsequently, should be taken into consideration when measuring the traits of any planets.
Exoplanet Watch is a good way for the general public to help astronomers in one of the crucial thrilling fields in science in the present day. As Zellem noted:
I hope this program lowers limitations to science for lots of people and evokes the following technology of astronomers to affix our subject.
Backside line: Do you wish to assist NASA research exoplanets? Now you possibly can, with the Exoplanet Watch citizen science mission. All you want is a telescope or a smartphone.
