To work this out, scientists first measure the planet's radius as it passes in front of a star, which allows them to estimate its size. To work out its mass, they look at how much the planet's orbit causes the star to 'wiggle'.
The next step is to see whether the planet is temperate, with a climate mild enough to support liquid water on the surface. This is revealed by the amount of light a planet receives, along with its orbit.
TFAW survey II: 6 Newly Validated Planets And 13 Planet Candidates From K2 - Astrobiology
The TFAW survey is an ongoing project that aims to re-analyze all light curves in K2 C1-C8 and C12-C18 campaigns with a wavelet-based detrending and denoising method, and the period search algorithm TLS to search for new transit candidates not detected in previous works.
We have analyzed a first subset of 24 candidate planetary systems around relatively faint host stars (10.9 < Kp < 15.4) to allow for follow-up speckle imaging observations.
Could distant planets be fit for human habitation?
Due to the threat of the current climate crisis, scientists have begun to search for distant planets, outside our Solar System, where humans could potentially settle.
Dr Assaf Hochman, from the Fredy & Nadine Herrmann Institute of Earth Sciences at the Hebrew University of Jerusalem (HU), in collaboration with Dr Paolo De Luca at the Barcelona Supercomputing Center, and Dr Thaddeus D Komacek at the University of Maryland, have successfully analysed the ...
Student uses NASA data to reveal new details on planets in other solar systems
Jared Siegel, B.S. '22, spent six months analyzing data taken by a NASA spacecraft.
"As the results kept taking shape, they just got more exciting," said Siegel, who graduated this spring.
The results of the research for Siegel's undergraduate thesis have been published in The Astronomical Journal .
Simple laser system could help astronomers find new planets on the cheap | E&T Magazine
A system for finding new, Earth-like planets using a simple laser has been developed by researchers at Heriot-Watt University.
The laser emits light at one billion pulses per second and comprises just two mirrors and a sapphire crystal containing a small amount of titanium.
A new discovery by scientists will narrow down the number of planets where it makes sense to look ...
“It’s possible this planet’s condition could be a bad sign for planets even further away from this type of star,” said Michelle Hill, an astrophysicist at the University of California, Riverside, and co-author of the study.
However, Hill is somewhat optimistic, saying that if a planet is far enough from an M dwarf, it could “potentially retain an atmosphere.”
The Effect Of Collisional Erosion On The Composition Of Earth-analog Planets In Grand Tack models: ...
Impact-induced erosion of the Earth’s early crust during accretion of terrestrial bodies can significantly modify the primordial chemical composition of the Bulk Silicate Earth (BSE, that is, the composition of the crust added to the present-day mantle).
In particular, it can be particularly efficient in altering the abundances of elements having a strong affinity for silicate melts (i.e. incompatible elements) as the early differentiated crust was preferentially enriched in those.
NASA Provides a Timelapse Movie Showing How the Universe Changed Over 12 Years - Universe Today
The Universe is over 13 billion years old, so a 12-year slice of that time might seem uneventful. But a timelapse movie from NASA shows how much can change in just over a decade.
NASA launched WISE—the Widefield Infrared Survey Explorer —in 2009. WISE found star clusters, thousands of dwarf planets, and helped discover Earth’s Trojan asteroids, among other things. When WISE ran out of primary coolant in 2011, NASA put the spacecraft in hibernation.
