ON-SCREEN TEXT: NASA's TESS mission discovered something new about a fascinating stellar pair just 130 light-years away.
ON-SCREEN TEXT: Both of the young stars host planets.
ON-SCREEN TEXT: The stars are of similar age and are traveling in nearly the same direction ...
ON-SCREEN TEXT: ... so scientists think they're stellar siblings, born from the same gas cloud.
ON-SCREEN TEXT: TESS detected the stars' planets by looking for regular dips in starlight.
ON-SCREEN TEXT: These dips are called transits.
ON-SCREEN TEXT: One system, called TOI 2076, has three mini-Neptunes ...
ON-SCREEN TEXT: ... planets larger than Earth but smaller than Neptune.
ON-SCREEN GRAPHIC: TOI 2076 b; size: 3.2x Earth, orbit: 10.4 days
ON-SCREEN GRAPHIC: TOI 2076 c; size: 4.4x Earth, orbit: over 17 days
ON-SCREEN GRAPHIC: TOI 2076 d; size: 4.1x Earth, orbit: over 17 days
ON-SCREEN TEXT: The other, called TOI 1807, hosts a single planet about twice Earth's size.
ON-SCREEN GRAPHIC: TOI 1807 B; size: 1.8x Earth, orbit: 0.5 days
ON-SCREEN TEXT: We don't know much about these planets yet ...
ON-SCREEN TEXT: ... but scientists are excited to study them further with missions like NASA's Hubble and James Webb space telescopes.
ON-SCREEN TEXT: These worlds could help us better understand how young planetary systems evolve.
ON-SCREEN TEXT: In the meantime, TESS will continue hunting for faraway worlds and help unlock even more of their secrets.
