Shown here are the galaxies NGC 4038 and NGC 4039, together known as the Antennae Galaxies. Located about 60 million light-years from Earth—a relatively short distance in cosmic terms—this pair is among the most closely studied examples of interacting galaxies visible in the night sky.

Roughly a billion years ago, their powerful gravitational pull drew them into an unusually close encounter. While individual stars within the galaxies seldom collide, vast clouds of interstellar gas do crash into one another, triggering intense bursts of new star formation.

In a dark sky location, you can see around 2,500 to 3,000 stars at once with the naked eye, compared to only a few dozen in a city. The Milky Way appears as a distinct, hazy, luminous band stretching across the horizon.

Beyond countless stars, observers can see planets, constellations, the Andromeda Galaxy, the Orion Nebula, and even phenomena like zodiacal light and airglow.

A Harvard University professor has said 3I/ATLAS, a comet shrouded in controversy, experienced a sudden "nongravitational" acceleration while passing around the sun, which he believes adds to other potential evidence that 3I/ATLAS is "alien technology."

Scientists have captured the first ever photo of an electron's whizzing orbit within a hydrogen atom, thanks to a unique new microscopy technique.

You are able to see a real probability distribution of an electron cloud of the hydrogen atom. #physics

The results from a 2018 survey published by YouGov polled 8,215 US adults. Approximately 18% of adults aged 18-24 years have some belief in a flat, or otherwise shaped, Earth. This is staggering considering that only 4% of adults aged 55 or older believe in a flat, or otherwise shaped, Earth.

Of those aged 18-24, around 2% have always believed in a flat Earth, and an additional 2% believe the Earth is flat with doubts. 5% prescribe to a sphetical-shaped Earth, but have doubts in the scientifically-established model.

The remaining 84% of adults aged 18-24 have always believed that the Earth is round, compared to 94% of those aged 55 and older.

Photographs of the pink Moon of April 1st, 2026.

This effect is caused by the Moon being low on the horizon, its light passes through more of the Earth's atmosphere. This thicker air scatters blue light away and allows longer wavelengths, such as pink, red, or orange light, to pass through.

Captured by NASA’s Hubble Space Telescope, this image highlights the Egg Nebula’s striking contrasts of illumination and shadow, created by material recently expelled from its central star. Situated about 1,000 light-years away in the constellation Cygnus, the nebula surrounds a star hidden behind a thick veil of dust—evoking the appearance of a bright core embedded within a darker shell. Hubble’s resolution reveals fine structural details that offer insight into how evolving stars shed matter and shape their surrounding environments.

At the center of this Hubble Space Telescope image lies the galaxy cluster SDSS J1038+4849, located more than 4.5 billion light-years from Earth. The arrangement of galaxies and gravitational lensing arcs gives the cluster a striking resemblance to a smiling face.

NASA is tracking a small asteroid named 2023 DW, roughly 164 feet in diameter, which has a very low (approx. 1-in-770) chance of impacting Earth on February 14, 2046.

It is currently considered a "1" on the Torino scale, indicating an extremely unlikely event with no immediate cause for public concern.

NASA has released a new set of ultra–high-resolution images of Jupiter, providing one of the most detailed views ever captured of the planet’s dynamic atmosphere.

The images reveal sharply defined cloud bands stacked in complex layers, immense storm systems spanning thousands of kilometers, and continuous turbulence driven by extreme atmospheric energy, far exceeding anything observed on Earth.

Beyond their visual impact, these images offer significant scientific insight. Subtle color variations correspond to differences in chemical composition, including ammonia, methane, and other trace compounds, allowing researchers to better map Jupiter’s atmospheric structure. The distinct banding patterns also trace powerful jet streams that regulate the planet’s global climate and drive its chaotic weather.

Notably, the Great Red Spot remains prominent, a long-lived anticyclonic storm that has persisted for over 300 years.

Continued observation of this feature, alongside newly resolved atmospheric details, helps scientists refine models of gas giant dynamics and deepen understanding of planetary weather systems across the solar system.

Astronomers have discovered the exoplanet TOI-1452 b, about 100 light-years away, that appears to be a strong candidate for a global “water world.” Roughly 70% larger than Earth and orbiting a red dwarf within a binary star system, the planet shows physical characteristics that differ markedly from rocky terrestrial planets. Observations from NASA’s Transiting Exoplanet Survey Satellite (TESS), supported by ground-based follow-ups, indicate a density and atmospheric profile consistent with an extensive, planet-wide ocean rather than exposed continents.

If confirmed, this scenario implies a world where water could extend hundreds of kilometers beneath the surface, reshaping assumptions about planetary diversity and habitability. Such environments are of particular interest because liquid water is central to astrobiology, offering parallels to conditions thought to exist on early Earth. Findings like these expand the scope of the search for life, highlighting that potentially habitable environments may arise in forms far different from familiar terrestrial analogues.

The first flower grown in space was a Zinnia (Zinnia hybrida), which bloomed on the International Space Station (ISS) in January 2016 as part of NASA's Veggie experiment.

Cultivated by astronaut Scott Kelly, these flowers were chosen to test how plants grow in microgravity, providing insights for future long-duration missions to Mars.

NASA's James Webb Space Telescope (JWST) captured stunning, detailed infrared images of Uranus, highlighting its faint rings, seasonal north polar cap, and atmospheric storms.

Using NIRCam, Webb resolved 11 of the 13 known rings—including the faint, inner Zeta ring—and captured 14 of its 27 known moons, revealing a dynamic ice giant. #space #NASA #astronomy

The NASA/ESA Hubble Space Telescope captured a "smiling" galaxy cluster, SDSS J1038+4849, featuring two bright orange "eyes" (galaxies) and a "smile" arc.

This cosmic emoticon is created by strong gravitational lensing, where the immense gravity of the cluster bends and distorts light from background galaxies, forming the smile shape. #astronomy #space
