'Extreme' exoplanet found orbiting hot blue star - CNN

(CNN) Taking a second glance in space can be rewarding, especially when a closer look reveals a weird exoplanet.

A warm Jupiter orbiting a cool star | Penn State University

UNIVERSITY PARK, Pa. – A planet observed crossing in front of, or transiting, a low-mass star has been determined to be about the size of Jupiter. While hundreds of Jupiter-sized planets have been discovered orbiting larger sun-like stars, it is rare to see these planets orbiting low-mass host stars and astronomers think this discovery could help them better understand how these giant planets form.

"This is only the fifth Jupiter-sized planet transiting a low-mass star that has been observed and the first with such a long orbital period, which makes this discovery really exciting," said Caleb Cañas, lead author of the paper and a doctoral student at Penn State and NASA Earth and Space Science Fellow.

SpaceX's next astronaut launch for NASA pushed back to Oct. 31 | Space

We'll have to wait a bit longer for SpaceX's first operational crewed mission to the International Space Station to get off the ground.

The target launch date for that flight, known as Crew-1 , has been pushed from Oct. 23 to early Halloween morning (Oct. 31), NASA officials announced Monday (Sept. 28).

"The new target date will deconflict the Crew-1 launch and arrival from upcoming Soyuz launch and landing operations. This additional time is needed to ensure closure of all open work, both on the ground and aboard the station, ahead of the Crew-1 arrival," NASA officials wrote in a statement .

Many things are taking place:

How NASA's New Telescope Will Help Astronomers Discover Free-Floating Worlds | Science |

As astronomers discover more and more planets in galaxies far, far away, they are increasingly confronted with a curious subset of orbs that are free-floating and not connected to or orbiting a particular star. Further complicating matters is that within that group, most of what they have found are gassy, Jupiter-sized (read: large), planets; few resemble rockier planets like our own Earth.

First discovered in 2003, these potential free-floating planets are elusive and difficult to detect from the existing ground-based observatories.

Stars Without Planets Are More Numerous Than You Might Think

The star cluster NGC 6604 is shown in this image taken by the Wide Field Imager attached to the ... [+] 2.2-metre MPG/ESO telescope at the La Silla Observatory in Chile. NGC 6604 is the bright grouping towards to the upper left of the image. It is a young star cluster that is the densest part of a more widely scattered association containing about one hundred brilliant blue-white stars.

The planetary paradigm has shifted so quickly and so radically in the last quarter century that is easy to forget that only a few decades ago, one would be hard-pressed to find any professional astronomer who would stake their careers on the idea that most stars harbor planets. But although the overwhelming majority of stars may harbor some form of planet, not all stars are capable of forming planets.

'Earthgrazer' meteor filmed skimming Earth's atmosphere and bouncing into space

Cameras have captured the rare sight of an 'Earthgrazer' meteoroid skimming our planet's atmosphere before "bouncing" back into space.

This particular meteoroid got hair-raisingly close , flying as low as 56 miles up in the sky, far below any orbiting satellites, before bouncing back out again.

The space rock whizzed through the night sky above Northern Germany and the Netherlands in the early hours of 22 September.

In the early hours of 22 Sept over N. Germany & the Netherlands, a meteoroid got down to 91 km in altitude - far below orbiting satellites - before it 'bounced' back into space

First planetary candidate outside our galaxy found

The Milky Way has enough exoplanets to keep TESS busy for years, but can we prove there are even more planets in galaxies far, far away?

No planet tied to an orbit around a star (or stars) in another galaxy has ever been detected, until now. Astronomers did suspect rogue planets were meandering through a galaxy 3 billion light years away back in 2018. However, there was uncertainty in the darkness of space, even though it was lit up by a powerful quasar near that galaxy. Gravitational lensing amplified an object when something warped light.
