Sky Tour Radio Presents: Mailbag #1
Sunday May 6th, 2018
In this episode of SkyTour Radio, we discuss exoplanet NGTS-1b in our weekly roundup, then turn our attention back to Earth as we take a closer look at the Hawaiian volcano, Kilauea and what this recent eruption means for the planet.
We also open the listeners mailbag, where we answer past questions from the KGRA Listener Lounge in an in depth manner, tying it in to past episodes and discussions.
NGTS-1b is a confirmed hot Jupiter-sized extra-solar planet orbiting NGTS-1, a red dwarf star about half the mass and radius of the Sun, every 2.65 days.The NGTS-1 system is about 600 light-years from Earth in the Columba constellation,discovered by the Next-Generation Transit Survey.
The discovery of NGTS-1b by Daniel Bayliss and Peter Wheatley from the University of Warwick’s Astronomy and Astrophysics Group represents only the third gas giant found to transit an M-dwarf star, and the largest planet in comparison to its host star.
Prior to this discovery, astronomers didn’t think that a star of this diminutive size could produce a planet so large. Scientists figured that small stars are able to churn out rocky planets, but that dwarf star systems didn’t possess enough overall material to form Jupiter-sized planets.
Researchers speculate that NGTS-1, during its formative stages, featured an unusually thick proto-planetary disk. though the how and why still remain a mystery.
Located along the southern shore of the island, the volcano is between 300,000 and 600,000 years old and emerged above sea level about 100,000 years ago.
Kilauea is one of the most active and well-monitored volcanoes in the world.It’s been erupting on and off for hundreds of thousands of years, and has been erupting continuously since 1983, with only occasional pauses of quiet activity. This particular “episode” of the eruption began in the late afternoon of May 3, in a part of Leilani Estates, a subdivision near the town of Pahoa.
Since Monday, hundreds of earthquakes, most of them around 2.0 magnitude, have been recorded in the area. The series of quakes came after a collapse of a crater floor of Puu Oo. Since that collapse, about 250 earthquakes were reported in the area into Tuesday evening, according to a Hawaiian Volcano Observatory status report.
Mailbag # 1
In our first open mailbag segment, we answer questions from the KGRA Listener Lounge from past episode, relating to previous discussion and topics, like the creation and destruction of planets, dangers we may face from the universe here on Earth and the impact future discoveries will have on humanity.
Join us weekly to have some of your questions answered, on http://KGRARadio.com
Sky Tour 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.
