SkyTour Radio Presents: Super Jupiters And Methane On Mars
Sunday June 10th, 2018
In this episode of SkyTour Radio, we continue with our weekly exoplanet roundup,by looking at two of the biggest jovian exoplanets we have found by discussing HR 2562 b and GQ Lupi b. HR 2562 being the most Massive exoplanet found to date while GQ Lupi b is the largest and what that difference means. We also reviewNASA’s latest announcement regarding the Curiosity Rover finding at Gale crater this past week and what that means for the future of astronomy.
HR 2562 b
First observed in 2016 using the Gemini Planet Imager, HR 2526b is a sub-stellar companion of debris disk host star HR 2562. Initially categorized as brown dwarf, its exact mass is unknown however according to NASA Exoplanet Archive,with a mass of 30 MJ, it is listed as the most massive planet and has a luminosity of about two-thousands of a percent of a solar mass.
GQ Lupi b
One of the first extra-solar planet candidates to be directly imaged, its discovery was announced in April 2005. GQ Lupi b is a possible extra-solar planet or brown dwarf orbiting the star GQ Lupi and has a spectral type between M6 and L0,corresponding to a temperature between 2,050 and 2,650 kelvins.
It is believed to be several times more massive than Jupiter, though, due to the theoretical models which are used to predict planetary masses for objects inyoung star systems like GQ Lupi b, the mass cannot be precisely specified. Models place GQ Lupi b’s mass anywhere between a few Jupiter masses and 36 Jupiter masses.
Curiosity is a car-sized rover designed to explore Gale Crater on Mars as part of NASA’s Mars Science Laboratory mission. The rover’s goals include an investigation of the Martian climate and geology; assessment of whether the selected field site inside Gale Crater has ever offered environmental conditions favorable for microbial life, including investigation of the role of water; and planetary habitability studies in preparation for human exploration.
The Curiosity Rover has lasted so long, it was able to study repeating trends on Mars,including the periodic release of methane during the martian summer. This is potential historic as it means what is replenishing the methane is possibly a biological process, or life.
June 7th 2018, NASA’s announced that organic matter has been found on Mars in soil samples taken from 3 billion-year-old mud stone in the Gale crater. This could signal a record detailing ancient life, a food source for life or something that exists in the place of life. Researchers believe these findings to be “breakthroughs in astrobiology.”
SkyTour Radio explores the Universe in a down to Earth manner explaining the science we know in fun and bite-sized terms. Science is for everyone and people shouldn’t require an advanced degree to understand as long as it is delivered in an easy to follow way. From Black Holes to Extraterrestrial Life, we will explore the Universe like never before. Join us to check out such things as how stars form, how they live and, how our fate is intertwined with theirs. On the extraterrestrial life front, we will be speaking to the UFO and science arena’s top researchers and bring UFOlogy into the 21st century.
