Newly theorized eggshell planets could develop ultra-thin, ultra-smooth outer layers, according to a study published in the Journal of Geophysical Research: Planets. Remarkably, three such worlds may already have been detected. Over the past two decades, astronomers have confirmed more than 4,500 ex

Expert in designing compact nuclear fission reactors? NASA and the U.S. Department of Energy want your expertise to fit one inside a 4x6 meter rocket fairing. A Nuclear Reactor for the Moon NASA and its partners aim to establish a permanent presence on and around the Moon, necessitating a robust lun

Mechanical engineering professor Jake Abbott from the University of Utah warns that Earth could soon form its own rings—but made of space debris rather than ice and rock like Saturns. He also proposes an innovative way to tackle orbital waste. Rings of Space Junk In an interview with the Salt Lake T

Researchers have pinpointed how solar wind—a stream of charged particles from the Sun—triggers water molecule formation on dust grains from asteroids that impacted the early Earth. Earth stands out among rocky planets for its abundant water, sparking decades of debate on its origins. One leading hyp

The Universe holds many mysteries, particularly its origins—a question that captivates scientists and philosophers alike. Was it created? If so, could the Creator have embedded a message for us? Renowned astrophysicist Michael Hippke from Germanys Sonneberg Observatory investigated this by analyzing

In 2020, SpaceX CEO Elon Musk expressed strong confidence in launching the first crewed Mars mission by 2026. Heres a precise breakdown of how these historic interplanetary voyages will unfold. Founded in 2002 by Elon Musk with the vision of making humanity multi-planetary, SpaceX is developing the

Chinas Yutu-2 rover, exploring the Moons far side, has encountered a intriguing cube-shaped rock on the horizon. Detailed analysis by mission scientists will soon reveal its origins. On January 3, 2019, China achieved a historic first by softly landing on the Moons far side with its Change-4 mission

Astronomers have announced the discovery of TOI-2109b, the gas giant with the shortest orbital period ever recorded. This scorching world completes one orbit around its star in just 16 hours—and its spiraling inward, potentially facing destruction soon. Known as hot Jupiters, these massive gas plane

French Economy Minister Bruno Le Maire announced that ArianeGroup will invest in developing small reusable rockets, aiming to compete directly with SpaceX, the industry pioneer in this technology. Ariane rockets once dominated geostationary satellite launches for Europe. Today, strategic missteps an

A team of astronomers has announced the observation of a long-theorized type of binary star system featuring extremely low-mass (ELM) white dwarfs. The findings are detailed in Monthly Notices of the Royal Astronomical Society. A new type of star Nearly 97% of stars in the universe end their lives a

Astronomers at the German Aerospace Centers Institute for Planetary Research have discovered GJ 367b, a rocky exoplanet orbiting its star so closely that it completes a full revolution in just 7.7 hours. Ultrashort-period planets like this remain poorly understood, making this TESS detection a signi

Astronomers at the University of California, San Diego, have uncovered a highway network across the Solar System, enabling significantly faster travel than previously thought possible. A Highway Network Shaping Comet Paths Imagine traversing the Solar System in record time. In a study published in S

James Webb Space Telescope (JWST) mission experts have successfully completed fueling operations ahead of its December 22 launch from French Guiana. The process spanned about ten days. Following multiple delays due to technical challenges and budget constraints, the JWST remains on schedule for laun

Asteroid 4660 Nereus, roughly the size of the Eiffel Tower at 330 meters wide, will make a close approach to Earth soon. Experts at NASAs Jet Propulsion Laboratory confirm it poses absolutely no risk, offering a prime chance for astronomers to study it up close.Near-Earth Asteroid from the Apollo Gr

Leading researchers caution that extraterrestrial microbes could hitchhike on spacecraft, potentially contaminating Earth as Solar System exploration intensifies.Risks of Biological InvasionHuman activities have accelerated biological invasions, spreading microbes, invertebrates, vertebrates, and ex

Using ESOs Very Large Telescope, astronomers have directly imaged a giant planet orbiting a massive binary star system visible to the naked eye with an ultra-hot primary star. This discovery challenges long-held assumptions that planets cannot form around such extreme environments. A Giant Among Gia

Asteroid 4660 Nereus will safely pass Earth in days, crossing its orbit without threat. Closely monitored by space agencies, it holds vast mineral deposits worth billions. A Frequent Visitor Near Earth Recently, weve highlighted near-Earth asteroid 4660 Nereus, measuring 330 meters across—comparable

NASA has awarded Northrop Grumman a $3.19 billion contract for solid rocket boosters to power its Space Launch System (SLS) on future lunar missions through 2031. While other providers may support later flights, this deal ensures reliable propulsion for key Artemis program launches. NASAs most power

Astronomers at the University of Texas have identified a supermassive black hole at the core of Leo I, a dwarf satellite galaxy of the Milky Way. This black hole rivals the mass of our galaxys central one. Findings are detailed in The Astrophysical Journal. Discovered in 1950 by R. G. Harrington and

Didymos and its moon Dimorphos (also known as Didymoon) pose no risk to Earth. However, to highlight their scale, the European Space Agency (ESA) has released compelling visualizations as part of ongoing planetary defense efforts.Asteroids can approach unexpectedly, as seen in July 2019 when a 100-m
