Clouds, hellish temperatures, endless nights? Characterizing the atmosphere of exoplanets, planets that orbit stars other than the sun, is a formidable task.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.

35 years ago Sally Ride became the first American woman in space. But rather than focus on her own extraordinary achievements, her passion became boosting the number of girls pursuing STEM. Another pioneering astronaut remembers her friend and colleague.

People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.

It’s almost impossible for any human to spot something unknown or unusual in the massive amount of data collected by our telescopes. So we’re teaching an intelligent machine to search the data for us.

Stargazing seems such a quiet, calm activity. But whether our eyes can see or not, those stars out there are in constant flux. Time-domain astronomy studies how cosmic objects change with time.
Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy.

Each fortnight I get the amazing opportunity to speak about my top stories in space on ABC Breakfast News TV but for those of you who hate early mornings I wanted to make sure you got to hear of these…
2015 saw us complete our exploration of all nine planets (including dwarf planet Pluto) in our solar system.
