Planet (COSMOS: The SAO Encyclopedia of Astronomy)

Exoplanet or extrasolar planet is a planet outside the Solar System. The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. As of 2022, there are more than 5,000 confirmed exoplanets. — Wikipedia

Exoplanet Junket - This week NASA released a new project that they’ve dubbed the Exoplanet Travel Bureau. The core of the project consists of a set of interactive 360° images that show “imagined” surfaces of five exoplanets (TRAPPIST-1e, Kepler-16b, Kepler-186f, PSO J318.5-22 and HD 40307 g). Here are three articles about the experience. This Brilliant Interactive From NASA … Continue reading Exoplanet Junket
TRAPPIST-1 - You’ve probably heard that NASA has found a trove of “Earth-like” planets circling the TRAPPIST-1 system roughly 40 light years away, but just in case you haven’t, here’s a short video from NASA/JPL about the discovery.

On June 13, 2019, the number of known exoplanets passed 4000 according to the NASA Exoplanet Archive! This animation celebrates their discoveries in time and converted them into music. A circle appears at the position of each exoplanet as it is discovered with a colour that indicates which method was used to find it. The size of the circle indicates the relative size of the planet’s orbit and the pitch of the note indicates the relative orbital period of the planet. Planets with longer orbital periods (lower orbital frequencies) are heard as low notes and planets with shorter orbital periods (higher orbital frequencies) are heard as higher notes. The volume and intensity of the note depends on how many planets with similar orbital periods were announced at the same time. The discovery of a single planet will be quiet and soft while the discovery of many planets with similar periods is loud and intense. — SYSTEM Sounds

Science

Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and the processes of their formation. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. — Wikipedia

TESS finds its first rogue planet
on April 25, 2024 at 5:37 pm
Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising discovery; their first free-floating—or rogue—planet. The planet was discovered using gravitational microlensing where the planet passed in front of a star, distorting its light and revealing its presence.

on April 23, 2024 at 8:07 pm
In celebration of the 34th anniversary of the launch of NASA's legendary Hubble Space Telescope on April 24, astronomers took a snapshot of the Little Dumbbell Nebula (also known as Messier 76, M76, or NGC 650/651) located 3,400 light-years away in the northern circumpolar constellation Perseus. The photogenic nebula is a favorite target of amateur astronomers.
Will we know if TRAPPIST-1e has life?
on April 23, 2024 at 5:18 pm
The search for extrasolar planets is currently undergoing a seismic shift. With the deployment of the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS), scientists discovered thousands of exoplanets, most of which were detected and confirmed using indirect methods.

on April 22, 2024 at 4:25 pm
Can tidal forces cause an exoplanet's surface to radiate heat? This is what a study accepted to the Astronomical Journal hopes to address as a team of international researchers used data collected from ground-based instruments to confirm the existence of a second exoplanet residing within the exoplanetary system, HD 104067, along with using NASA's Transiting Exoplanet Survey Satellite (TESS) mission to identify an additional exoplanet candidate. The study is available on the arXiv preprint […]

on April 22, 2024 at 3:31 pm
Despite surface temperatures hot enough to melt lead, lava-spewing volcanoes, and puffy clouds of sulfuric acid, uninhabitable Venus offers vital lessons about the potential for life on other planets, a new paper argues.
