Space

The three Red Monsters represent the core findings of this work – these extremely massive and dusty galaxies in the first billion years after the Big Bang indicate that the early Universe is forming stars more efficiently than expected. Image taken by the James Webb Space Telescope.

Steven Butcher, Technology Service Corporation space robotics and mechanisms engineer, performs an inspection of the Robotic Servicing of Geosynchronous Satellites (RSGS) payload after completing testing in the cryogenic thermal vacuum chamber at the U.S. Naval Research Laboratory’s Naval Center for Space Technology in Washington, D.C. Oct. 4, 2024. Once on-orbit, the RSGS payload will inspect and service satellites in geosynchronous orbit.

This Hubble Space Telescope image captures a triple-star system, which can host potentially-habitable planets. Our nearest stellar neighbour, the Alpha Centauri system, includes three stars.

In the simulations, a tight ring of polar vortices forms at around 55 degrees latitude, the equivalent of Earth’s Arctic circle. After forming, the vortices head toward the poles in a tightening ring, shedding vortices as the circle closes, eventually leaving only a pair of vortices directly abutting the poles before they disappear altogether at solar maximum. How many vortices form and their configuration as they move toward the poles changes with the strength of the solar cycle.

Hubble and Webb Observations of Vega Circumstellar Debris Disk. [left]-A Hubble Space Telescope false-color view of a 100-billion-mile-wide disk of dust around the summer star Vega. Hubble detects reflected light from dust that is the size of smoke particles largely in a halo on the periphery of the disk. The disk is very smooth, with no evidence of embedded large planets. The black spot at the center blocks out the bright glow of the hot young star. [right]-The James Webb Space Telescope resolves the glow of warm dust in a disk halo, at 23 billion miles out. The outer disk (analogous to the solar system’s Kuiper Belt) extends from 7 billion miles to 15 billion miles. The inner disk extends from the inner edge of the outer disk down to close proximity to the star. There is a notable dip in surface brightness of the inner disk from approximately 3.7 to 7.2 billion miles. The black spot at the center is due to lack of data from saturation.

In the new communication system from researchers at Chalmers University of Technology, in Sweden, a weak optical signal (red) from the spacecraft's transmitter can be amplified noise-free when it encounters two so-called pump waves (blue and green) of different frequencies in a receiver on Earth. Thanks to the researchers' noise-free amplifiers in the receiver, the signal is kept undisturbed and the reception on Earth becomes record-sensitive, which in turn paves the way for a more error-free and faster data transmission in space in the future.
