ALMA helps answer questions about how massive stars form

Astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to answer a major question about stars. That question is, do stars that are much more massive than our sun form in the same way as smaller stars. Astronomers have observed still-forming stars similar in mass to the sun as they gain material from the surrounding clouds of dust and gas relatively quickly. The masses of incoming material form a disk orbiting the young star that feeds the star at a fast pace for it to digest.

Proxima Centauri generates a massive solar flare

Proxima Centauri generates a massive solar flare

The closest star to the sun is called Proxima Centauri. Scientists recently spotted the largest solar flare ever recorded from that star. Proxima Centauri is four light-years, more than 20 trillion miles, from our sun and hosts at least two planets.

Super-Earth orbits a red dwarf star in only 2.4 days

Astronomers have made an interesting discovery of a super-Earth planet that's orbiting a red dwarf star called GJ-740. A red dwarf star is significantly cooler than the Sun, with a surface temperature between 2400 and 3700 kelvin. That is a difference of over 2000 degrees cooler than the Sun.

Researchers detect CNO neutrinos in the sun’s core

Researchers detect CNO neutrinos in the sun’s core

Researchers from Princeton have announced that they have been able to detect CNO neutrinos, tiny particles pointing to the presence of carbon, nitrogen, and oxygen inside the core of the sun. The particles are said to reveal the last missing detail of the fusion cycle that powers the sun and other stars. These are a rare type of neutrinos known as "ghost particles" because they're able to pass through most matter without leaving a trace.
