Pulsar planets were the first planets outside the solar system ever discovered, but they now appear to be very rare. What makes a pulsar planet so uncommon?
The authors of today’s astrobite try and assess how much knowledge you can actually gain about the first four Harry Potter books by only watching the fourth movie. In other words, what can you learn about planet formation by looking at observations of exoplanets?
Spinning stars can potentially double the number of seasons that a planet experiences due to surface temperature variations on the stellar surface.
We now know that our nearest stellar neighbor may harbor an Earth-like exoplanet. The Breakthrough Starshot initiative plans to get spacecraft there in only 20 years. However, the “empty” space between us and our nearest star is not completely empty, and the material in the path of these spacecraft may have catastrophic consequences for the mission.
On KELT-16b you would melt. I would melt too. A look at an exciting and newly discovered Hot Jupiter, and why KELT-16b is a valuable addition to the group of boiling gas giant planets, and a fantastic target for future atmospheric studies.
Planets form with molten surfaces; but how does this ocean of magma affect the planet’s atmosphere?
