starts to explode –

As recently as 1990, we didn’t know of any planets outside our solar system. Today, with 5000+, we delve into the herbs of how they form.

This two-color image shows an illustration of the protoplanetary disk around the young star FU Orionis, which has been imaged multiple times by the Hubble Space Telescope but years apart. The disk has changed, indicating that it is entering a more advanced stage of evolution, as planets form and the material available to form and grow evaporates, sublimates, and explodes away.

  • We once wondered whether planets are common, uncommon, or extremely rare in the universe: a question that was largely unanswered until very recently, when NASA’s Kepler mission revealed planet abundance.
  • But as it turns out, despite the huge numbers of planets discovered, not only do not all stars have planets, but all planets don’t have stars either.
  • In this fascinating 90-minute conversation with Dr. Camper Schwartz, we delve into the details of planet formation, go straight to the frontiers and look even further into the great unknown.

Although it seems like a long time ago, we had no idea since the early 1990s whether planets in the universe were universal, common, uncommon, or even extremely rare. While some data sets seemed to suggest that every star in the universe had planets around it, we now know that’s not true at all. Many, and perhaps most, stars have planets, but many other stars do not have planets. In addition, the number and types of planets that exist, including planets that have no origin stars at all, are still being investigated, and the field of planet formation has become very active.

With new data from infrared and radio observatories, including JWST and ALMA, we’re learning a lot about the planets forming in the universe, including the conditions under which they form and what the various important and dominant considerations are. Here as our latest guest on the podcast Begins with A Bang, to help us separate what is known from what is still curious, Dr. Kamber Schwarz, Postdoctoral Researcher at MPIA Heidelberg.

There’s still a lot to learn, but cool, how much we know today compared to the early ’90s is amazing. Enjoy this look at the limits of what we know about how planets form, and I hope it leaves you wondering what else we’ll learn in the very near future!

Our model of the universe, which is dominated by dark matter and dark energy, explains almost everything we see. approx. That’s what’s left.

LIGO can detect overtones and mergers of the least massive, but not the largest, black holes. Here’s how pulsars can help.

The James Webb Space Telescope is about to begin its science operations. This is what interests astronomers.

For a thousand light-years in all directions, there is a “bubble” in the center of which is the Sun. Here’s the story behind it.

In the latest edition of the podcast Begins with A Bang, we talk with soon-to-be Dr. Ariana Long about galaxies, from birth to today.

One small change could have made a big difference.
