Medicine & TechnologyExoplanet TOI-674b first caught the attention of astronomers because it is big and orbits around a small star. Now, scientists discovered that its atmosphere has water vapor, which is unusual for a planet orbiting far from its star.
A study detected the presence of a new exoplanet GJ 367b just outside of our solar system. The planet is rich in iron an has density similar to Mercury. It could complete a revolution around its red dwarf parent star in less than a day.
In recent years, scientists have discovered a number of planets that, if not the title of "twin of the Earth," at least claim to be its closest equivalents.
Astronomers using NASA's powerful Chandra X-Ray Observatory telescope may have recently discovered evidence of the first exoplanet circling a star outside of the Milky Way galaxy.
NASA just shared a video of future space tourism when civilians can go beyond Earth's orbit to visit other planets and moons that could one day become vacation destinations for humans.
