Unraveling the Enigma of Shrinking Exoplanets: Insights from Kepler and Retired NASA Telescope

Data from NASA's Kepler Space Telescope suggests that the absence of exoplanets between 1.5 and two times the size of Earth may be due to core-powered mass loss. Scientists have found evidence that the cores of sub-Neptune exoplanets push away their atmospheres from the inside out, causing the exoplanets to shrink. This phenomenon occurs when radiation emitted by the planet's hot core interacts with the atmosphere, causing it to fade away slowly. The study used data from the Kepler Space Telescope's extended mission, K2, and found that core-powered mass loss is the leading explanation for atmospheric loss in sub-Neptunes. Further research is needed to fully understand this process.

The Shrinking Mystery of Exoplanets: NASA's Findings

NASA scientists have discovered a mysterious gap in the size of exoplanets, with hardly any planets between 1.5 to 2 times the width of Earth. Research suggests that some sub-Neptunes shrink due to radiation from their cores pushing their atmospheres away, causing them to lose mass and become as small as super-Earths. The exact mechanism for this atmosphere loss is still unclear, but two hypotheses, core-powered mass loss and photoevaporation, are being considered. Data from NASA's Kepler Space Telescope supports the core-powered mass loss hypothesis, but recent work suggests that both processes may be operating. Further research is needed to fully understand the phenomenon.

Unraveling the Mystery: NASA's Discovery of Shrinking Exoplanets

Researchers using data from the Kepler Space Telescope have discovered that some exoplanets are shrinking due to the loss of their atmospheres, likely caused by radiation from their cores. This finding helps explain the observed size gap in exoplanets and suggests a significant atmospheric loss process different from previously theorized photoevaporation. The study provides evidence supporting the theory of core-powered mass loss, where radiation emitted from a planet's hot core pushes the atmosphere away over time. The research also highlights the ongoing mystery of the missing exoplanets between super-Earths and sub-Neptunes and the need for further investigation.

Unraveling the Mystery: NASA's Findings on Shrinking Exoplanets

Astronomers have discovered that some exoplanets are losing their atmospheres, causing them to shrink. This phenomenon, known as "core-powered mass loss," occurs when radiation from the planet's hot core pushes away its atmosphere from within. This process can transform a puffy, sub-Neptune planet into a rocky super-Earth. The findings explain why there are few exoplanets with sizes between a super-Earth and sub-Neptune. The study analyzed exoplanet data collected by NASA's Kepler 2 mission and suggests that core-powered mass loss is the likely reason behind atmospheric escape on these planets.

Unraveling the Mystery: NASA's Kepler Telescope Reveals Clue to Shrinking Exoplanets

NASA scientists may have discovered the reason behind the shrinking of planets beyond our solar system. There is a size gap where planets seem to shrink past a certain range, and the data from NASA telescopes suggest that the cores of these planets might be pushing their atmospheres away, causing them to shrink. This phenomenon, known as core-powered mass loss, could explain the mystery of the missing exoplanets. However, further research is needed to fully understand the mechanisms behind this process.

Unveiling the Mystery: NASA Data Sheds Light on Exoplanet Shrinkage

A new study using NASA's Kepler Space Telescope suggests that some exoplanets are losing their atmospheres and shrinking due to core-powered mass loss. The study focuses on the "size gap" between super-Earths and sub-Neptunes and provides evidence that the cores of these planets are pushing away their atmospheres from the inside out. The researchers observed star clusters Praesepe and Hyades and found that nearly 100% of stars in these clusters still have sub-Neptune planets or planet candidates, indicating that core-powered mass loss is the most likely explanation for the shrinking of these planets. Further research is needed to fully understand the mechanisms behind this phenomenon.
