Through direct comparison with images from Hubble, you can start to see the exquisite detail and clarity Webb provides.
An artist’s concept of an astronaut walking on Mars. But what would happen if the astronaut weren’t wearing a space helmet?

Mars is the fourth planet from the Sun and one of our closest neighbors in space. But it’s not a very welcoming place for an Earthling to visit.

The Hubble Space Telescope could gaze back 13.4 billion years, and with the JWST we expect to improve on this possibly to 13.55 billion years.

Clouds, hellish temperatures, endless nights? Characterizing the atmosphere of exoplanets, planets that orbit stars other than the sun, is a formidable task.
Plus, the tactics the food industry is using to boost sales of ultra-processed foods in middle-income countries. Listen to The Conversation Weekly.

India may land on the Moon this coming year, while Nasa will launch its new, powerful rocket farther into space than any other human rated spacecraft.
Science fiction offers readers a way to rethink social dilemmas.

Fantasy fiction provides more than escapism for young readers.
The launch of Hubble Space Telescope on April 24, 1990. This photo captures the first time that there were shuttles on both pad 39a and 39b.
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.
An enhanced image of galaxy clusters.
New research using the Hubble Space Telescope reveals that galaxies may be forming at faster rates than previously believed.
Portrait of Ada Lovelace – mathematician and poet.

Poets and scientists don’t occupy separate poles in the quest to understand the universe. In many ways, they sing from the same hymn sheet.
Mission specialist Sally Ride became the first American woman to fly in space.
NASA's Goddard Space Flight Center
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.
Gravity of a white dwarf star warps space and bends the light of a distant star behind it.
NASA, ESA, and A. Feild (STScI
Astronomers report the first ever measurement of light bending around a star other than our own.
The truth is we don’t really know if space goes on forever – but maybe, one day, we will find out.
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.
Composite image of suspected water vapour plumes erupting at the seven o’clock position off the limb of Jupiter’s moon Europa.
There’s now strong evidence that Europa might be a worthwhile place to search for life.
All is not calm in the cosmos.
ESA/Hubble and NASA
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.
2015 was a year where we expanded our view of the universe, embraced new technologies and got a hint of the profound changes to come.
The light shining through an exoplanet’s atmosphere can give us a hint of whether the planet supports life.
NASA, ESA, and G. Bacon (STScI)
A hint of oxygen and a whiff of methane in a distant exoplanet’s atmosphere may be the first evidence we discover of alien life.
