The seven rocky planets orbiting the red dwarf star TRAPPIST-1 have remarkably similar densities, suggesting they likely have similar compositions, too.
Located about 40 light-years from Earth, TRAPPIST-1 hosts seven rocky planets that are about the size of Earth or smaller — the largest group of roughly Earth-size planets ever found in a single stellar system.
Earlier studies measured the mass and diameter of the TRAPPIST-1 planets, and found they are rocky, or terrestrial, like Earth. However, a new study measured the density of the rocky worlds in greater precision, suggesting that all of the planets are about 8% less dense than Earth, according to a statement from NASA's Jet Propulsion Laboratory.

White Dwarf Atmospheres Might Contain the Pulverized Crusts of Their Dead Planets - Universe Today
Astronomers have developed a new technique to search for exoplanets – by looking for their crushed up bones in the atmospheres of white dwarfs. And it’s working.
The search for planets outside the solar system, known as exoplanets, has one significant limitation: we can only find exoplanets that exist right now. But our universe has been hanging around for over 13 billion years, and many generations of planetary systems have come and gone in that vast expanse of cosmic time.
High schoolers help discover 4 new alien planets | Space
Two Massachusetts high schoolers — 16-year-old Kartik Pinglé and 18-year-old Jasmine Wright — have helped discover four new alien planets , a new study reports.

"By the end of the program, the students can say they've done active, state-of-the-art research in astrophysics," SRMP director Clara Sousa-Silva, a cosmochemist at MIT, said in a CfA statement .
Pinglé and Wright worked with Tansu Daylan, a postdoctoral researcher at MIT's Kavli Institute for Astrophysics and Space Research and the lead author of the new paper. Daylan and his colleagues — the study has dozens of co-authors — scrutinized observations of the sunlike star HD 108236 made by NASA's Transiting Exoplanet Survey Satellite (TESS).
Aquarius Stellium February 2021 - Astrology Meaning & Horoscope
In English? Basically, we can expect a lot of excitement and drama until the Sun moves into Pisces on February 18. This is a time of reflection and emotional detachment for us all. And on a global scale, the Aquarius stellium confirms what we already know about the COVID-19 pandemic: Social distancing (a very Aquarian concept) is more important than ever.

Astronomers Uncover New Details About the Remarkable Seven Rocky Planets of TRAPPIST-1
Measuring the mass and diameter of a planet reveals its density, which can give scientists clues about its composition. Scientists now know the density of the seven TRAPPIST-1 planets with a higher precision than any other planets in the universe, other than those in our own solar system. Credit: NASA/JPL-Caltech
Precise measurements reveal that the exoplanets of the system discovered by ULiège researchers have remarkably similar densities, which provides new clues about their compositions.
High schoolers discover four planets orbiting nearby star
Two Massachusetts high schoolers are getting praised for making a major astronomical discovery — finding four new planets outside our Solar System.
Kartik Pinglé, 16, and Jasmine Wright, 18, helped confirm the existence of the exoplanets and recently published a scientific paper on their findings.

To conduct the research, the bright duo was paired with a real-world scientist as part of the Student Research Mentoring Program at the Center for Astrophysics, Harvard & Smithsonian.

Five Giant Planets Orbit Nearby Sun-Like Star | Astronomy | Sci-News.com
Astronomers using ESA's CHaracterising ExOPlanet Satellite (CHEOPS) have discovered a fifth planet around the bright, Sun-like star HD 108236.

HD 108236 is a star of spectral and luminosity type G3V located 211 light-years away in the southern constellation of Centaurus.
Also known as TOI-1233, TIC 260647166, and HIP 60689, the star is 12% smaller than our Sun and 13% less massive.
In 2020, four large planets were discovered around HD 108236 using data from NASA's Transiting Exoplanet Survey Satellite (TESS).
