Planets may Start Forming Before the Star is Even Finished - Universe Today
Planets form from the accumulation of countless grains of dust swirling around young stars. New computer simulations have found that planets begin forming earlier than previously thought, when a planet’s star hasn’t even finished forming yet.
To make a planet you need to do a lot of gluing , going from tiny grains of dust invisible to the human eye to objects thousands of kilometers across. Prevailing theories of planetary formation assumed that this gluing process begins after a protostar had settled down, but new research is challenging that view.

Scientists discover new exoplanet with an atmosphere ripe for study -- ScienceDaily
An international group of collaborators, including scientists from NASA's Jet Propulsion Laboratory and The University of New Mexico, have discovered a new, temperate sub-Neptune sized exoplanet with a 24-day orbital period orbiting a nearby M dwarf star. The recent discovery offers exciting research opportunities thanks to the planet's substantial atmosphere, small star, and how fast the system is moving away from the Earth.
The research, titled TOI-1231 b: A Temperate, Neptune-Sized Planet Transiting the Nearby M3 Dwarf NLTT 24399, will be published in a future issue of The Astronomical Journal. The exoplanet, TOI-1231 b, was detected using photometric data from the Transiting Exoplanet Survey Satellite (TESS) and followed up with observations using the Planet Finder Spectrograph (PFS) on the Magellan Clay telescope at Las Campanas Observatory in Chile.
NASA's Juno Probe Flew By Jupiter's Moon Ganymede : NPR

Jupiter's moon Ganymede had a visitor from Earth on Monday. NASA's Juno spacecraft zoomed by in the afternoon, just 645 miles above the surface of the solar system's largest moon.
It's the first time a probe has made a close-up visit to Ganymede since the Galileo mission flew by in 2000.
Twinkle is the first privately-funded space telescope set to hunt exoplanets
Blue Skies Space is counting down to 2024 when the world's first commercial orbiting telescope platform, Twinkle, will provide an essential new class of satellite in the growing search for habitable exoplanets in our galaxy.
With funding rounds finalized and satellite construction to start early next year, Twinkle will provide faster, next-generation monitoring and analysis equipment in a much more accessible form than the Hubble Space Telescope or the now-retired Spitzer Space Telescope.
Helium rain probably falls inside Jupiter and Saturn - Futurity
"Our experiments suggest that deep inside Jupiter and Saturn, helium droplets are falling through a massive sea of liquid metallic hydrogen," says Gilbert (Rip) Collins. "That is a pretty amazing thing to think about next time you look up at Jupiter in the night sky." (Credit: NASA/JPL/Space Science Institute)
New experiments with lasers reveal evidence supporting the existence of helium rain inside planets composed primarily of hydrogen and helium, such as Jupiter and Saturn.

Bad Astronomy | The planet K2-146c discovered due to its gravity pulling on another planet
In 1990, not a single planet outside our solar system was known. Now, not only do we know of thousands, but we have also have an almost embarrassing number of ways to find them .
You may have heard of the transit method , where a planet passes in front of its star, and we see a dip in the amount of starlight, like a mini-eclipse. This is the most successful method so far, and gives us the radius of the planet. You may also know the radial (or reflex) velocity method , where a planet tugs on its star gravitationally as it orbits, which we can see as a Doppler shift in its light. This gives us the planet's mass.
