Cracking Mars’ Ancient Water Cycle
How much water did Mars have in its ancient past and when did it disappear? This is what a recent study published in Geophysical Research Letters hopes to address as an international team of scientists investigated Mars’ ancient water cycle processes, including its transport mechanisms between the surface and subsurface. This study has the potential to help scientists better understand ancient Mars and whether the Red Planet could have had the ingredients for life as we know it.
For the study, the researchers used computer models to simulate the length of time that liquid water on the surface of Mars billions of years ago required to go from the surface to the subsurface, specifically to mile-deep aquifers. While this same process takes only a few days on Earth, the researchers estimated that it took between 50 to 200 years on Mars for liquid water to go from the surface to the subsurface aquifers.
Chandra diagnoses cause of fracture in galactic ‘bone’
Astronomers have discovered a likely explanation for a fracture in a huge cosmic “bone” in the Milky Way galaxy, using NASA’s Chandra X-ray Observatory and radio telescopes.
The bone appears to have been struck by a fast-moving, rapidly spinning neutron star, or a pulsar. Neutron stars are the densest known stars and form from the collapse and explosion of massive stars. They often receive a powerful kick from these explosions, sending them away from the explosion’s location at high speeds.
Enormous structures resembling bones or snakes are found near the center of the galaxy. These elongated formations are seen in radio waves and are threaded by magnetic fields running parallel to them. The radio waves are caused by energized particles spiraling along the magnetic fields.
“Mining the Moon Begins”: US Firm’s Robot to Extract Rare Helium-3 and Launch Payloads Back to Earth for Futuristic Energy Use
IN A NUTSHELL 🌕 Interlune, a Seattle-based startup, plans to extract helium-3 from the moon, aiming to revolutionize clean energy and quantum computing. 🚀 The company has developed a prototype excavator capable of digging up to ten feet into lunar soil, refining helium-3 directly on the moon for efficiency. 🔋 Helium-3 offers potential for nuclear
Deepnight AI-Powered Night Vision: Revolutionizing Visibility in Complete Darkness
Deepnight’s Algorithm-intensified image enhancement for NIGHT VISION
Instead of using expensive image-intensification tubes, this startup is using ordinary low light sensors coupled with special computer algorithms to produce night vision. This will bring night vision to the general public. At present, even a generation 2 monocular costs around $2000, while a generation 3 device costs around $3500. The new system has the added advantage of being in color, instead of monochromatic. Hopefully, this will pan out, and change the situation for Astronomy enthusiasts worldwide.
Lucas Young, CEO of Deepnight, showcases how their AI technology transforms a standard camera into an affordable and effective night vision device in extremely dark environments.

Stretched in a cross pattern: Our neighboring galaxy is pulled in two axes, new evidence indicates
Researchers at Nagoya University in Japan have discovered that Cepheid variable stars in our neighboring galaxy, the Small Magellanic Cloud (SMC), are moving in opposing directions along two distinct axes. They found that stars closer to Earth move towards the northeast, while more distant stars move southwest.
This newly discovered movement pattern exists alongside a northwest-southeast opposing movement that the scientists previously observed in massive stars.
These complex bidirectional movements along two different axes indicate that the SMC is being stretched by multiple external gravitational forces—its larger neighbor, the Large Magellanic Cloud (LMC), in one direction and another currently unknown mechanism in the other. The findings are published in the journal The Astrophysical Journal Letters.
