Happy 20th Birthday to Hubble’s ACS Instrument!

Happy 20th Birthday to Hubble’s ACS Instrument!

The Advanced Camera for Surveys instrument onboard the Hubble Space Telescope is celebrating twenty years of service this week. Plus, a new look at an old lunar rock, gas rings around an aging star, all the rockets from around the world, and this week in rocket history, we look back at the 1962 Orbiting Solar Observatory, led by Nancy Grace Roman.

Mars Could Have Supported Life Longer Than Thought

Mars Could Have Supported Life Longer Than Thought

A NASA-funded simulation of early Mars revealed that the climate three billion years ago on the red planet was very similar to Earth now, with a stable ocean in the northern hemisphere. This new timeline would have given life another 500 million years to develop. Plus, a dwarf galaxy, Saturn’s aurorae, a Soyuz launch, and an interview with Dr. Adam Szabo, mission scientist for the Parker Solar Probe.

Newly Discovered Bright Transient Radio Source is a Mystery

Newly Discovered Bright Transient Radio Source is a Mystery

Scientists using the Murchison Widefield Array in Australia recently discovered an extremely bright source of radio waves, releasing bursts of energy three times an hour. That timing makes the object behave unlike anything else seen to date, leaving the research team with a new mystery to unravel. Plus, everything else is about water today, all over the solar system, and we present this week’s What’s Up segment.

Massive Thwaites Glacier in Antarctica at Risk of Collapse

Massive Thwaites Glacier in Antarctica at Risk of Collapse

A team of scientists collected cores and modeled ice cliff failure and found that Thwaites Glacier in Antarctica is melting more quickly than ever and could be at risk of collapse, threatening global coastlines with almost a meter of sea-level rise. Plus, new results from Percy, and this week’s What’s Up.
