We may find signs of life a mere 31 light-years away.
- The TESS satellite recently identified a nearby super-Earth sitting in the habitable zone of its star.
- TESS isn't equipped to make the sensitive measurements necessary to characterize the planet's atmosphere, but models suggest the planet could have running water, a major indicator that it can host life.
- The upcoming James Webb Space Telescope will be able to look at this planet in greater detail and assess whether life exists on it or not.
Some have suggested that there is no hidden giant out there.
- Some objects at the edge of our solar system have unusual orbits — they cluster together suggesting a large celestial body is pushing them close together.
- Instead of a massive unfound planet, it may be the gravitational pull from an equally massive disc of small, icy objects.
- Researchers created a model of such a disc that explained everything.
Scientists examined data from 20 years ago to reach a startling new conclusion.
- Observations made by the SOHO spacecraft over 20 years ago lead to a new discovery.
- The Earth has a hydrogen envelope as part of its outer atmosphere called the geocorona.
- The geocorona stretches well past the Moon, reveals a study.
It has already found several bizarre planets outside of our solar system.
- The Kepler program closed down in August, 2018, after nine and a half years of observing the universe.
- Picking up where it left off, the Transiting Exoplanet Survey Satellite (TESS) has already found eight planets, three of which scientists are very excited about, and six supernovae.
- In many ways, TESS is already outperforming Kepler, and researchers expect it to find more than 20,000 exoplanets over its lifespan.
Between Carl Sagan's laughter, the brainwaves of somebody in love, and a live theremin concert, humanity has sent a lot of data out into the stars.
- Ever since we've had the capability, humanity has been desperately trying to make contact with other life in the universe.
- While we've been beaming out information passively through our television and radio broadcasts, we've also sent more intentional messages.
- Looking at these messages tells us how humanity wants to think of itself and what kind of relationship we hope to have with alien life.
