Given the typical orbit of an observatory about L2, the observational baseline of ~1.5 × 10⁶ km between L2 and Earth results in an instantaneous parallax of ~10″–100″, even for the most distant of ...

Trans-Neptunian objects are the most distant solar system objects viewable from Earth. With some good equipment, a bit of luck, a bit of persistence and clear skies, you should be able to see some.

An artist’s rendition of a trans-Neptunian Object imagines the sun in the far, far distance. Some people in the aerospace business like engineering. Others prefer science. Jeralyn Gibbs ...

It has not been detected formally. Instead, astronomers have inferred its presence from perceived perturbations of the orbits of some Trans-Neptunian Objects (TNOs). The planet is estimated to be ...

Thanks to JWST, we've learned key details about methanol — a key building block for organic compounds necessary for life — on distant icy worlds. In a distant corner of our solar system called ...
