AI Thread Summary
Scientists have recently discovered the smallest exoplanet, measuring just one-fifth the size of Pluto. This discovery was highlighted on PhysicsWeb, emphasizing the significance of detecting such small celestial bodies. The detection was facilitated by observing small wobbles in the pulsar's movement, allowing for precise Doppler shift analysis. This finding raises hopes for the existence of similar modest-sized planets orbiting regular stars. The excitement surrounding this discovery underscores the ongoing advancements in exoplanet research.

Read about the discovery of the smallest (1/5th of the Pluto-size) exoplanet. This was just posted on PhysicsWeb, so it is very fresh. I also included some explanatory links, the first goes to the webpage of one of the discoverers...

that's interesting
four modest-size planets going around a pulsar
thanks for posting the link, marlon.

I guess that it is easier to detect small wobbles by a pulsar
because one can do dopplershift analysis very accurately
using the clockpulse of the pulsar

it makes one hopeful that there may be plenty of modest-size planets circling ordinary (not pulsar) stars as well
 
Twenty percent the size of Pluto... wow! That's quite amazing.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
