Mysterious Tessera Terrain on Venus Could Be the Remains of Giant Ancient Impacts

Breaking News, Climate Actions, Space

In the chaotic early days of the Solar System, planets endured a relentless barrage of cosmic collisions. Most of the rocky worlds including Mercury, Mars, and Earth's Moon still bear scars of these ancient impacts in the form of vast craters and impact basins. However, Venus has been a strange outlier, with scientists finding no evidence of large craters over 300 kilometers wide. This missing piece of Venus's violent past has puzzled researchers for years. A recent study now suggests that these long-sought impact structures may indeed exist on Venus but look very different from our expectations. Geologist Vicki Hansen of the Planetary Science Institute and her team propose that a peculiar formation called the Haastte-Baad Tessera could be Venus’s largest and oldest impact structure. Lo...

Sun Enters Solar Maximum Triggering Strongest Geomagnetic Storm in Two Decades

Breaking News, Disasters, Space

NASA, NOAA, and the International Solar Cycle Prediction Panel have confirmed that the Sun has entered the peak phase of its 11-year cycle, known as Solar Cycle 25. This period, called the solar maximum, is characterized by heightened solar activity, including an increase in sunspots and solar eruptions. The solar maximum, which began earlier this year, is expected to last for about a year, posing both exciting research opportunities and challenges for technology and infrastructure on Earth. What is Solar Maximum? During the solar maximum, the Sun’s magnetic poles flip, and the number of sunspots and solar flares surge. These flares, along with coronal mass ejections (CMEs), can send vast amounts of charged particles into space, which interact with Earth's magnetic field. When these ...

NASA Downplays Safety Concerns Despite Watchdog’s Warning on International Space Station Cracks and Leaks

Breaking News, Environment, Space

Despite its own inspector general's report warning of significant air leaks and cracks in the International Space Station (ISS), NASA appears to be minimizing the gravity of the situation. The Washington Post reported that NASA's recent internal assessment highlighted aging issues in the Russian segment of the ISS, pointing out cracks in the tunnel leading to that section. The report expressed concerns about the increasing severity of air leaks, which have grown worse over time. The inspector general’s report identified these leaks as a "top safety concern," citing that their ongoing increase could pose long-term risks to the space station's integrity and the safety of astronauts. While cracks in space station structures can result in air loss, endangering the crew's environment, NASA h...

Astronomers Discover Tiny Exoplanet Orbiting Barnard’s Star, Just 6 Light-Years Away

Breaking News, Disasters, Space

In a groundbreaking discovery, scientists have found a new exoplanet orbiting Barnard’s Star, the nearest single star to our Solar System, located just 5.96 light-years away. This small, rocky world, named Barnard b, has a mass of only 37% that of Earth, making it one of the smallest exoplanets ever detected. Although uninhabitable, the discovery marks a significant step toward finding Earth-sized planets scattered across the galaxy. Barnard b is incredibly close to its host star, completing an orbit every 3.15 days at just 0.02 astronomical units (AU) from the red dwarf. Despite Barnard’s Star being much cooler than our Sun, this proximity makes the planet too hot to sustain liquid water or life as we know it. However, the discovery is still a scientific marvel, as detecting such small...

New Study Reveals How Supermassive Black Holes Rip Stars Apart in Spectacular Fashion

Breaking News, Disasters, Space

Supermassive black holes at the centers of galaxies, including our own Milky Way, have long been known to occasionally devour nearby stars, leading to a dramatic process called a tidal disruption event (TDE). A new study, published today in The Astrophysical Journal Letters, has provided the most detailed simulations yet of this violent phenomenon, shedding light on the complex process that unfolds over the course of a year. Tidal disruption events occur when a star ventures too close to a black hole and is stretched and torn apart by its immense gravitational forces a process known as "spaghettification." The star is shredded into long, thin strands, and about half of its material is drawn toward the black hole, forming a hot, luminous swirl of matter called an accretion disc. The othe...

Venus and Earth A Tale of Twin Planets with Divergent Destinies: Study Says

Breaking News, Environment

Venus and Earth often referred to as planetary twins, have evolved into starkly contrasting worlds. While Earth is lush and life-sustaining, Venus is a hostile environment with toxic clouds, acid rain, crushing atmospheric pressure, and searing temperatures. Despite their superficial similarities, these differences run deep. Unlike Earth, Venus lacks tectonic plates the shifting, grinding sections of Earth's crust that play a crucial role in maintaining its climate and fostering the continents. This absence of tectonic activity on Venus has been a significant factor in the divergence between the two planets. However, the geological past of Venus remains a mystery, particularly the formation of its oldest surface regions, known as tesserae. Recent research by scientists, including geo...

Emergency on the ISS? Leaked Audio of Training Exercise Triggers Brief Earth Panic

Breaking News, Disasters, Space

Audio of a flight surgeon dealing with an emergency on the International Space Station (ISS) while she was stuck in traffic triggered a brief panic on the evening of June 12 CDT. The unnamed speaker appeared to be conducting a phone call with an unheard conversant, discussing a situation in which an unnamed commander would require hyperbaric treatment after an event that left them with decompression sickness. "Unfortunately, the prognosis for commander is relatively tenuous, I'll say, to keep it generic," the speaker is heard saying. ISS mission control has now confirmed that the audio was a ground simulation that was broadcast to the ISS livestream channel by mistake, and all crew members were safely asleep at the time of the broadcast. The audio, clipped from the livestream a...

Japan’s Obayashi Corporation Aims for 2050 Completion of Space Elevator to Revolutionize Space Travel

Breaking News, Space, Thoughts & Talks

Imagine a long tether linking Earth to space, launching us to orbit at a fraction of the cost and slingshotting us to other worlds at record speed. That's the basic idea behind a space elevator. Instead of taking six to eight months to reach Mars, scientists have estimated a space elevator could get us there in three to four months or even as quickly as 40 days. The concept isn't new, but engineering such a structure is a monumental challenge, and many issues beyond technology stand in the way. Japan's Ambitious Plan The Japan-based Obayashi Corporation, known for constructing the world's tallest tower, the Tokyo Skytree, announced in 2012 its goal to build a space elevator. The company projected that construction on the $100-billion project would begin by 2025, with operations st...
