James Webb Space Telescope

After years of setbacks, the James Webb Space Telescope will finally launch next month. NASA has given the green light to begin fueling the observatory for launch, after engineering teams found no sign of damage from an incident last week.

Astronomers have spotted two “invisible” galaxies hiding near the dawn of the universe. The team used radio waves to peer behind a curtain of dust, and the find suggests that there were far more galaxies in the early universe than previously thought.

The launch of the James Webb Space Telescope has suffered yet another delay – but at least this time, it’s only a few days. NASA says that additional testing of the instrument now needs to be conducted after an incident during launch preparations.

NASA has finally set a date for the launch of the James Webb Space Telescope (JWST). If all goes to plan, the long-awaited flagship mission will blast into orbit on December 18, 2021, from French Guiana onboard an Ariane 5 rocket.

It looks like the James Webb Space Telescope might actually launch in October, for real this time. The perennially delayed instrument has completed its final tests and is now being prepped for shipment to the launch facility.

Scientists may be able to detect the presence of dark matter by searching for anomalous heat signatures from distant alien worlds. Dark matter is an enigmatic, invisible substance that is thought to make up around 80 percent of the universe’s mass.

How exactly supermassive black holes got so big remains a mystery, but a new study suggests they may have been born from supernovae of hypothetical, primordial stars far bigger than any around today. And we might soon be able to detect the leftovers.

Space exploration in 2021 will see some major milestones to look forward to. From maiden flights to fiery endings, long-awaited launches to history-making first steps, here are some of the biggest upcoming events in space exploration this year.

A next-generation space observatory has inched closer to lift-off, with NASA unfolding the James Webb Space Telescope’s five-layer sunshield in the same way it expects it to after arriving in orbit, as part of successful testing here on Earth.

NASA's James Webb Space Telescope has passed a major milestone, completing its prelaunch environmental testing after being subjected to weeks of acoustic and sine-vibration tests to determine whether it can withstand the rigors of a rocket launch.

NASA and ESA have announced that the launch of the James Webb Space Telescope has been delayed to October 2021. A recently-completed schedule risk assessment recommended the delay, due to challenges raised by the ongoing COVID-19 pandemic.

The James Webb Space Telescope has crossed another milestone on the path to its long-awaited launch. NASA engineers have now completed a deployment test, unfurling the telescope’s gigantic mirror into the configuration it will take in space.
