Exoplanets Don't Like Heavy Metals

6th Nov, 2018 - 76 views

Studies of planetary systems have indicated that star systems with high metallicity (think iron - actually anything heavier than helium) may preferentially form planets,but a new survey suggests there are many compact, multiple-planet systems for whi

Mars: Warmer with Water - Was it once Closer to the Sun?

10th Sep, 2018 - 1.1k views

The study of planetary systems around other stars suggests that planets can migrate closer or farther from their parent star, not staying in the orbit where they originally formed. Traces of water on Mars suggests that it may have been wetter, and pe

Finding Neutrinos with (an) IceCube

7th Aug, 2018 - 1.2k views

Super energetic neutrinos can be formed in exotic places, for example the accelerators in the core of galactic supermassive black holes. The IceCube neutrino detector array was built and deployed at the South Pole. The detectors are designed and posi

Climate Change on Alien Worlds: A Possible Great Filter? (Pt 2)

21st Aug, 2018 - 1.2k views

Is climate change inevitable on worlds with technological civilizations? Is planetary feedback from such a civilization a great filter? Our guest Dr Adam Frank will discuss his paper on the effects of planetary feedback on any possible alien civiliz

Climate Change on Alien Worlds -A Possible Great Filter?

24th Jul, 2018 - 1.3k views

While our search is still in its infancy, we haven't yet found any obvious signs of intelligent life in our galaxy. One reason could be that any aliens out there may not have made it past a stage in its development where climate change wipes them out

Moons and Exoplanets: The Same or Different Species?

10th Apr, 2018 - 1.5k views

Researchers using a new model are looking at what the second largest moon in our Solar System, Titan, would be like if it was in orbit around a Sun-like or Dwarf Star. How much would Titan change? Could it harbor life?

Raining Sunscreen? The Atmosphere of Kepler 13Ab

7th Nov, 2017 - 1.5k views

Kepler-13Ab is one of the hottest known planets, with a dayside temperature of nearly 5,000 degrees Fahrenheit and is located 1,730 light-years from Earth. It has an unusual atmosphere that appears to contain titanium oxide (like sunscreen). The sci

Shock Waves from the Sun: Space Weather in 3D

22nd Mar, 2018 - 1.5k views

Eruptions from the Sun cause Aurora and are the drivers of space weather throughout the solar system. These eruptions can create beautiful night time displays and interesting features in the atmospheres of the outer planets.

The Solar Corona: What Shape wilt have during the 2017 Eclipse?

10th Aug, 2017 - 1.5k views

In the United States, there will be an opportunity on August 21st 2017 to see a total or partial solar eclipse. Eclipses offer a rare opportunity to see the thin atmosphere around the Sun, known as the Corona. The moon moves in front of the sun f

Europa Plumes! Looking at Past Galileo Data

18th May, 2018 - 1.5k views

Astronomers were enthusiastic but cautious about the Hubble observations that suggested Europa had water plumes ejected from its icy surface.

New Evidence for a Large Exomoon around Kepler-1625b

10th Oct, 2018 - 1.5k views

Astronomers using Hubble Space Telescope data have new observations of a candidate exomoon associated with Kepler-1625b. If confirmed, this exomoon would be quite large, with a mass and radius similar to Neptune. The exoplanet Kepler-1625b is itsel
