Opportunity just saw its 5,000th sunrise on Mars!

It’s been a time of milestones for Mars rovers lately! Last month (on January 26th, 2018), NASA announced that the Curiosity rover had spent a total of 2,000 days on Mars, which works out to 5 years, 5 months and 21 days. This was especially impressive considering that the rover was only intended to function on the Martian surface for 687 days (a little under two years).

It Turns Out, Andromeda is Younger Than Earth… Sort Of

It Turns Out, Andromeda is Younger Than Earth… Sort Of

Since ancient times, astronomers have looked up at the night sky and seen the Andromeda galaxy. As the closest galaxy to our own, scientists have been able to observe and scrutinize this giant spiral galaxy for millennia. By the 20th century, astronomers realized that Andromeda was the Milky Way’s sister galaxy and was moving towards us. In 4.5 billion years, it will even merge with our own to form a supergalaxy.

Long-Lived Mars Rover Opportunity Keeps Finding Surprises

Long-Lived Mars Rover Opportunity Keeps Finding Surprises

NASA's Mars Exploration Rover Opportunity keeps providing surprises about the Red Planet, most recently with observations of possible "rock stripes."The ground texture seen in recent images from the rover resembles a smudged version of very distinctive stone stripes on some mountain slopes on Earth that result from repeated cycles of freezing and thawing of wet soil. But it might also be due to wind, downhill transport, other processes or a combination.

Starfish can see in the dark (among other amazing abilities)

Starfish can see in the dark (among other amazing abilities)

If you go down to the shore today, you’re sure of a big surprise. Many will have witnessed the presence of a starfish or two when visiting the seashore or a public aquarium. Starfish come in an exciting range of colours and sizes, but have you ever given a thought to how this multi-armed wonder manages to exist in our oceans when it’s so unlike the other animals we know?

When galaxies collide, size matters if you want to know the fate of our Milky Way

When galaxies collide, size matters if you want to know the fate of our Milky Way

Our Milky Way and the Andromeda galaxy – two giant galaxies in our local patch of the universe – are heading for an immense collision with each other in only a few billion years’ time. So which will dominate in this intergalactic tussle?

Starfighters Inc. has a deal with NASA to develop a training program for space tourists. The company currently has just one customer. With multiple companies planning to launch space tourists in the next few years, that will likely soon change.

Hubble Sees Neptune's Mysterious Shrinking Storm

Hubble Sees Neptune's Mysterious Shrinking Storm

Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm – once big enough to stretch across the Atlantic Ocean from Boston to Portugal – is shrinking out of existence as seen in pictures of Neptune taken by NASA’s Hubble Space Telescope.

New Stem Cell Study Could Be the Start of Personalized Cancer Vaccines

New Stem Cell Study Could Be the Start of Personalized Cancer Vaccines

Each year, the world invests billions of dollars into cancer research, but because cancer cells multiply rapidly and without limit, developing effective treatments for the disease is extremely difficult. Now, a new study published in the journal Cell Stem Cell may reveal a way we could create a cancer vaccine, essentially training our bodies to fight the disease before it even takes hold.

Dance of galaxies challenges current thinking on cosmology

Dance of galaxies challenges current thinking on cosmology

Scientists have a pretty good picture of how the universe formed and evolved – and how it is structured today. This knowledge all fits together nicely as a “standard cosmological model”, which has been able to successfully predict and describe many observational data in the universe. But now and then scientists discover something that threatens to tear down this valuable framework.

What is your real ‘biological age’, and what does this mean for your health

What is your real ‘biological age’, and what does this mean for your health

Age-based risk calculators that work out your “real biological age” are increasingly popular. We hear about body age on health shows like How to Stay Young; gyms promote reductions in metabolic age and fitness age; games and apps claim to lower your brain age; and researchers have developed specific organ measures like heart age, lung age and bone age.

A Lonely Beauty

A Lonely Beauty

Beauty, grace, mystery — this magnificent spiral galaxy has all the qualities of a perfect galactic Valentine. Captured by the NASA/ESA Hubble Space Telescope, the galaxy NGC 3344 presents itself face-on, allowing astronomers a detailed look at its intricate and elegant structure. And Hubble’s ability to observe objects over a wide range of different wavelengths reveals features that would otherwise remain invisible.
