Webb telescope sees the prelude to a supernova

March 21, 2023 Stephen Clark

A new image from the James Webb Space Telescope shows a rare glimpse of a massive star 15,000 light-years away shedding a halo of gas and dust, seeding the cosmos with elements necessary for forming other stars, planets, and the building blocks of life.

NASA blames recent Hubble woes on aging hardware

March 31, 2021 Stephen Clark

Hardware problems that cropped up earlier this month on the Hubble Space Telescope, now approaching the 31st anniversary of its launch, are the latest signs the observatory is showing its age.

Hubble resumes science observations after software error

March 12, 2021 Stephen Clark

NASA has partially restored the Hubble Space Telescope to science mode after a software error temporarily halted observations, but engineers continue studying a problem that kept the telescope’s aperture door from closing and a separate concern with Hubble’s main camera.

Jupiter looms large in spectacular Hubble image

September 18, 2020 Stephen Clark

The Hubble Space Telescope turned toward Jupiter last month, capturing colorful views of the giant planet and its icy moon Europa more than 400 million miles from Earth.

Hubble still going strong 30 years after launch

April 24, 2020 William Harwood

Thirty years ago Friday, the Hubble Space Telescope was launched aboard the shuttle Discovery with a famously flawed mirror, the opening chapter in an improbable saga of redemption and scientific discovery that revolutionized humanity’s view of the cosmos with jaw-dropping images now familiar to millions.

Hubble’s premier camera resumes observations

January 25, 2019 Stephen Clark

The most-used instrument on the orbiting Hubble Space Telescope is back in business after engineers on the ground determined a fault that halted the camera’s science observations earlier this month was caused by erroneous telemetry data, and was not a symptom of a hardware failure as initially suspected.

Controllers troubleshoot problem with Hubble camera

January 10, 2019 Stephen Clark

The partial shutdown of the U.S. government could complicate efforts to troubleshoot a suspected hardware problem with the Hubble Space Telescope’s premier science instrument, but officials are optimistic the camera will eventually be restored to operations, the head of the observatory’s science operations team said Wednesday.

Hubble Space Telescope in safe mode with gyro trouble

October 9, 2018 William Harwood

NASA has suspended science operations with the Hubble Space Telescope and put the observatory into protective “safe mode” while engineers troubleshoot problems with one of the spacecraft’s three remaining gyroscopes, used to help aim the telescope and keep it locked on target, officials said Monday.

Jupiter’s moons, black holes, exoplanets among JWST’s first scientific targets

December 4, 2017 Stephen Clark

The James Webb Space Telescope should start returning its first scientific results by the end of 2019, and scientists recently announced a slate of observations selected to whet the appetites of astronomers who will use the multibillion-dollar facility well into the 2020s.
