An analysis of the lightcurve of the microlensing event PA-99-N2 suggests the presence of a planet orbiting a star in the Andromeda Galaxy. [97] A controversial microlensing event of lobe A of the double gravitationally lensed Q0957+561 suggests that there is a planet in the lensing galaxy lying at redshift 0.355 (3.7 Gly). [98] [99]
Human presence in outer space began with the first launches of artificial object in the mid 20th century, and has increased to the point where Earth is orbited by a vast number of artificial objects and the far reaches of the Solar System have been visited and explored by a range of space probes.
The future of space exploration involves both telescopic and physical explorations of space by robotic spacecraft and human spaceflight.Near-term physical exploration missions, focused on obtaining new information about the Solar System, are planned and announced by both national and private organisations.
In April 2022, Planet Hollywood announced plans to offer more than 60,000 of its memorabilia, including photographs and movie posters, as NFTs under MetaHollywood. [27] In May 2023, the Planet Hollywood Restaurant located in the Forum Shops at Caesars, was permanently closed. The restaurant had been located at the Forum Shops for 29 years.
Being so far from the Sun, 2018 AG 37 moves slowly among the background stars and has been observed only nine times in the first two years. [5] It requires an observation arc of several years to refine the uncertainties in the approximately 700-year orbital period and determine whether it is currently near or at aphelion (farthest distance from ...

The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
Webb is designed primarily for near-infrared astronomy, but can also see orange and red visible light, as well as the mid-infrared region, depending on the instrument being used. [ 10 ] [ 11 ] It can detect objects up to 100 times fainter than Hubble can, and objects much earlier in the history of the universe , back to redshift z≈20 (about ...
