Uncle Segar is an expert on many things including the land, sea and sky. This knowledge is then captured in his artworks.
Publicly available data and collaborations between scientists have led to the discovery of a planet in a triple-star system.
The hottest exoplanet known so far has metals in its atmosphere – something scientists thought would be impossible.
Thanks to the discovery of five twinkling galaxies in a rare alignment, astronomers have been able to calculate — for the first time — the properties and geometry of an invisible gas cloud in space.
These results might lead us to revise our understanding of how galaxies stop forming their stars.
Cape astronomers were responsible for, among other things, the first measurement of the distance to a star; the first photographic sky survey and the accurate measurement of the distance to the sun.
The scariest beast in the universe has an insatiable appetite and shreds its victims.
Surprising findings on an exquisite and huge star system in our Milky Way suggest future potential for an extremely rare gamma-ray burst. This event has never been observed in our galaxy.
COVID-19 may have messed up school and shut down a lot of entertainment venues. But you can still brighten things up by doing a little stargazing at night, an astronomer says.
Towns and cities create an orange glow on the horizon at night. It’s so widespread that it even disturbs sea creatures.
If you could go right into the middle of the Sun, everything would be incredibly bright - and perhaps a little bit pink.
By 2025 Elon Musk wants to launch 12,000 satellites and corner the global Internet market. What will be lost is earth-based astronomy, the idea that space belongs to us all and the beauty of a starry sky.
Albert Einstein may have been the ultimate example of a visionary genius, but that did not stop him from twice losing his way due to beliefs that were perhaps not so scientific.
Has the Sun entered a stage of old age?
This observation means astronomers can now develop and test theories that explain how high-mass stars gain their mass.
The Dish in Parkes is scanning the southern Milky Way, searching for alien signals

Today we hear about the Parkes radio telescope's role in the search for alien life. Our guide is the irrepressible John Sarkissian, the scientist who's had his eye on The Dish since childhood.
If Betelgeuse explodes, it will become as bright as the full moon in a matter of days and be visible during day time.
NASA scientists have discovered a new planet orbiting around a nearby star that is in a habitable zone. But does this planet have liquid oceans that can support life?
Dark sky sites can inspire new generations of stargazers, but a better long-term solution would be connecting people with the night sky where they live.
