This movie is built from images taken over 10 days during the full perihelion encounter when the spacecraft was nearing the Sun's corona. The perihelion is a brief moment during the encounter time, when the spacecraft is at its closest point to the Sun. The movie is from orbit 10 and dates and distances are …
Evolving Views of Our Heliosphere Home
We can't see the heliosphere. We know where it starts but not really where it ends. And we are pretty certain that most stars, and therefore most planetary systems, are bounded by heliospheres, or "astropheres," as well. It has a measurable physical presence, but it is always changing. And although it is hardly well known, …
Touching the Sun
The Parker Solar Probe is the stuff of superlatives and marvels. Later this week, it will pass but 5.3 million miles from the sun -- much closer than Mercury or any other spacecraft have ever come -- and it will be traveling at a top speed of 101 miles per second, the fastest human-made object …
The Stellar Side of The Exoplanet Story
When it comes to the study of exoplanets, it's common knowledge that the host stars don't get much respect. Yes, everyone knows that there wouldn't be exoplanets without stars, and that they serve as the essential background for exoplanet transit observations and as the wobbling object that allows for radial velocity measurements that lead …
