The architecture and evolution of planetary systems are shaped in part by stellar flybys. Within this context, we look at stellar encounters which are too weak to immediately destabilize a planetary system but are nevertheless strong enough to measurably perturb the system’s dynamical state. We estimate the strength of such perturbations on secularly evolving systems using a simple analytic model and confirm those estimates with direct N-body simulations. We then run long-term integrations and show that even small perturbations from stellar flybys can influence the stability of planetary systems over their lifetime. We find that small perturbations to the outer planets’ orbits are transferred between planets, increasing the likelihood that the inner planetary system will destabilize.
Designs for a massive, 1,300 foot-tall rotating structure called “The Glass” were presented at a July 5 press conference held by Kyoto University researchers and Kajima Corporation. If completed artificial gravity building will be on Mars, and the other will be on the moon.
This is the story of how one man, with a controversial past as a Nazi believed he had the knowledge and vision to make Kennedy’s dream a reality.
BEIJING, June 29 (Reuters) — An uncrewed Chinese spacecraft has acquired imagery data covering all of Mars, including visuals of its south pole, after circling the planet more than 1,300 times since early last year, state media reported on Wednesday.
China’s Tianwen-1 successfully reached the Red Planet in February 2021 on the country’s inaugural mission there. A robotic rover has since been deployed on the surface as an orbiter surveyed the planet from space.
Among the images taken from space were China’s first photographs of the Martian south pole, where almost all of the planet’s water resources are locked.
It’s just a “speck of the universe.”
The first image from NASA’s James Webb Space Telescope offered humanity a stunning new view of the universe on Monday — a first-of-its-kind infrared image so distant in the cosmos that it shows stars and galaxies as they appeared 13 billion years ago.
President Joe Biden revealed the new image Monday at the White House alongside Vice President Kamala Harris and NASA officials. Dubbed “Webb’s First Deep Field,” it is the first full-color image from the $10 billion observatory that launched into space last year, and the highest-resolution infrared view of the universe yet captured.
The newly released full-color image highlights a stunning collection of ancient galaxies—and heralds a new age for astronomy.
The first image from the James Webb Space Telescope will be released in 45 minutes! 😱 Watch with us.
Last week, NASA administrator Bill Nelson told us we’d see the “deepest image of our Universe that has ever been taken” on July 12, thanks to the newly operational James Webb Space Telescope (JWST). And we know many of you excitedly marked the date in your calendar.
But over the weekend the space agency announced that they’d actually be releasing one the very first image a day ahead of schedule – at 5.30pm EDT (2130 UTC and 7.30am AEST on Tuesday 12 July).
The first image will be released by US President Joe Biden in a special live stream that you can view in real time below. We’ll be watching live and sharing the first image with all of you as soon as it’s available. Suffice to say, we can’t freaking wait!

Hello and welcome! My name is Anton and in this video, we will talk about an interesting achievement by the Australian researchers that may have managed to create a world’s first quantum integrated circuit.
