The team started out by trying to determine whether some of the exoplanet host stars identified with TESS were actually unknown binary stars. Physical pairs of stars that are close together can be mistaken for single stars unless they are observed at extremely high resolution.
Using the 'Alopeke and Zorro instruments on the Gemini North and South telescopes in Chile and Hawai'i, respectively, the team observed hundreds of nearby stars that TESS had identified as potential exoplanet hosts.
EarthSky | Planet makes a surprise photobomb
Astronomers said on June 28, 2021 that they were observing two planets orbiting a star some 50 light-years away, when a 3rd planet made a surprise photobomb of their image. The star is Nu2 Lupi .
Because Nu2 Lupi is such a bright star – so relatively close to us – these scientists called the photobombing planet:
Many nearby Earth-size exoplanets could be hiding in plain sight | Space
A team led by Katie Lester, a postdoctoral fellow at NASA's Ames Research Center, recently used ground-based high-resolution technologies to peer at points of light studied with NASA's Transiting Exoplanet Survey Satellite (TESS) mission.
TESS hunts for planets around nearby stars by watching for dips in their light caused when a planet transits, or passes in front of, a star.
Why You Need To Stay Outside After Watching A Sunset This Month: Bright Planets, A 'Buck Moon'
The Milky Way taken from the Isle Of Wight, UK. From the return of some bright planets to the night ... [+] sky to a great view of the Milky Way from dark sky destinations, here's why you need to stay outside after watching summer sunsets this July.
You don't think the height of summer is a great time to go stargazing? The nights may be short in the northern hemisphere, but there are some incredible sights waiting for anyone who takes the time to look up.
10 weirdest moons in the solar system | Space
All About Space magazine takes you on an awe-inspiring journey through our solar system and beyond, from the amazing technology and spacecraft that enables humanity to venture into orbit, to the complexities of space science.
All but two of our solar system 's planets have natural satellites of one sort or another. Earth's own moon , a beautiful but stark, dead world shaped by ancient volcanoes and countless impact craters, is undoubtedly the most familiar, but it's far from being the most interesting.
Study: Planets Capable of Sustaining Photosynthesis Are Extremely Rare | Evolution News
Earth is … the rocky planet with the largest PAR photon flux and with the highest exergetic efficiency. However, we also find that Kepler-442b receives a PAR photon flux slightly larger than the one necessary to sustain a large biosphere, similar to the Earth biosphere.
We know that Earth meets all of these requirements, but does Kepler-442b? At this point we simply don't know.
There Are Probably Almost Twice As Many Earth-like Planets As We Thought | IFLScience
Half the stars in the galaxy come in pairs. When it comes to searching for the most Earth-like planets, the light of the second star makes it hard to spot the planet's effects as it passes across one star's face. Image Credit: International Gemini Observatory/NOIRLab/NSF/AURA/J. da Silva
The 9 Wildest Planets in the Milky Way Give Us Insight Into the Mysteries of Deep Space
While these incredible feats of engineering have expanded our potential to learn about our cosmos, there's still so much outer space left to explore. Luckily, we do know some things about the mysterious, vast expanse overhead, including fun facts about our nearest planetary neighbors.
Planet with more water than Earth discovered during unique cosmic photobomb - SCIENCE News
The European Space Agency's (ESA) exoplanet-hunting Cheops satellite has found a third planet in a star system previously believed to have only two planets. The third planet, discovered in a unique photobomb, appears to contain large amounts of water clouds.
Astronomers came across the third planet as it moved across the star revealing details of a rare planet "with no known equivalent." This is the first time that an exoplanet with an orbit of over 100 days has been spotted transiting a star that is bright enough to be visible to the naked eye.
