NASA has successfully tested a powerful lithium-fed plasma thruster that reached 120 kW, more than 25× the power of the electric thrusters on NASA’s Psyche spacecraft.

The technology still needs major development, but NASA says future nuclear-electric versions could help reduce travel time to Mars.

So, 3 months isn't a demonstrated travel time yet, but it could be possible with a fully developed system.

Would you trust a future spacecraft powered by this technology for a trip to Mars?

A solar eclipse is a perfect cosmic alignment:

Sun → Moon → Earth. 🌑☀️

As the Moon moves between the Sun and Earth, its shadow falls across our planet.

On August 12, 2026, observers along a narrow path from Greenland through Iceland and Spain can experience totality, when the Moon completely covers the Sun.

Would you travel to see totality?

August 2026 has two eclipses on the calendar.

☀️ On August 12, a total solar eclipse will sweep across parts of Greenland, Iceland, northern Russia and Spain.

🌘 Just over two weeks later, on August 27-28, a partial lunar eclipse will be visible across large parts of the Americas, Europe and Africa.

🔭 Which one would you rather watch?

August 12, 2026 could be one of the most exciting nights of the year for skywatchers. A total solar eclipse will sweep across parts of Greenland, Iceland and Spain, and later that night the Perseid meteor shower reaches its peak with little to no moonlight interfering. 🌑🌠

Only 5 days remain until the August 12 Total Solar Eclipse.

The Moon's shadow will sweep across Greenland, Iceland, Spain, and parts of Russia, creating one of the most spectacular sky events of 2026.

If you're along the path of totality, you're in for an unforgettable view.

Who's excited for eclipse day?

Gamma Ray Bursts Cleanse Entire Star Systems

A planet nearly 48 light-years away has reached a major milestone in astronomy.

Scientists have confirmed that LHS 1140 b possesses an atmosphere, the first confirmed atmospheric detection on a rocky planet located within the habitable zone of another star.

The evidence comes from helium escaping into space, proving the planet has retained an atmosphere. While this doesn't mean the planet is inhabited, an atmosphere is one of the key ingredients scientists look for when assessing whether a world could support life.

This discovery marks an important step toward finding Earth-like planets beyond our Solar System.
Do you think LHS 1140 b could become our best candidate in the search for life, or will an even more Earth-like planet be discovered first?

Could a future on Mars make humanity more resilient?

In a July 2026 interview with The Economist, Elon Musk said a self-sustaining Mars colony could help reduce civilization-wide risks from pandemics, AI, and other global catastrophes. While the idea is speculative, it reflects his long-term vision of making humanity a multi-planetary species.

Do you think establishing a permanent colony on Mars is essential for humanity's future, or should we focus on solving Earth's problems first?

August 2026 will be one of the biggest months for eclipse enthusiasts.

A total solar eclipse will occur on August 12, followed just over two weeks later by a partial lunar eclipse on August 27–28.

The solar eclipse will bring daytime darkness along a narrow path across parts of Greenland, Iceland, Spain, Portugal, and Russia, while the lunar eclipse will be visible across large regions of the world, depending on your location.

If you could witness only one of these events, which would you choose, the total solar eclipse or the partial lunar eclipse?
