Durham University researchers find cataclysmic direct hit with Gaia Sausage sent Milky Way into its current positionAstronomers have found evidence that the Milky Way was flipped on its side following a direct hit from a wayward galaxy long before the solar system was born.The cataclysmic collision took place about 10bn years ago when the Milky Way was struck head-on by an incoming dwarf galaxy known – for purely astronomical reasons – as the Gaia Sausage.

• NASA released a high-resolution image of the Centaurus A galaxy to commemorate the fourth anniversary of the James Webb Space Telescope. • The image captures the aftermath of a massive cosmic collision that occurred approximately 2 billion years ago, resulting in the galaxy's unique, distorted shape. • This release highlights the telescope's ability to build upon previous astronomical foundations and provide deeper insights into galactic evolution.

• The Hubble Space Telescope has detected light from a distant galaxy known as MXDFz4.4, which researchers previously believed should have been invisible. • This "impossible" light suggests that the galaxy existed during a period when the early universe was thought to be opaque. • The discovery is significant because it may provide critical insights into the process of cosmic reionization, explaining how the universe transitioned from opaque to transparent billions of years ago.

• Vietnamese films have achieved a dominant 70.6% share of the local box office, according to Galaxy Studio CEO Dinh Thanh Huong. • The announcement was made during the DANAFF Industry Days, a new initiative by the Danang Asian Film Festival and the Vietnam Film Development Association. • The event connects major local studios, such as Galaxy Studio and BHD Vietnam Media Corp., with international distributors from the U.S., South Korea, Japan, and several Southeast Asian nations.

• Vietnamese films have achieved a dominant 70.6% share of the local box office market, according to Galaxy Studio CEO Dinh Thanh Huong. • This growth was highlighted during the DANAFF Industry Days, a new initiative by the Danang Asian Film Festival and the Vietnam Film Development Association. • The event connects major local studios, including Galaxy Studio, BHD Vietnam Media Corp., and CJ HK Entertainment, with international distributors from the U.S., South Korea, Japan, and Southeast Asia.

• NASA’s James Webb Space Telescope observed the edge-on starburst galaxy Messier 82, also known as the Cigar Galaxy or NGC 3034. • By peering through cosmic dust, the telescope pinpointed 16.5 million stars and revealed the galaxy's distended disk structure. • The intense star formation in M82 is believed to be the result of a galaxy merger, creating a unique, short-lived environment for astronomical study.

• The James Webb Space Telescope has detected intense, collision-driven "galaxy-killing winds" in ancient galaxies existing near the dawn of time. • These powerful winds appear to have caused early galaxies to "live fast and die young" by stripping away the gas necessary for star formation. • This discovery is significant as it provides a potential preview of the eventual death of the Milky Way and other similar galactic structures.

• Astronomers have traced a high-energy "ghost particle," known as a neutrino, back to a star-forming galaxy dubbed "Shadow Blaster." • The neutrino traveled for billions of years from a source located 11 billion light-years away, originating when the universe was only 3 billion years old. • This discovery is significant because Shadow Blaster would be the first individual dusty star-forming galaxy ever directly linked to a high-energy neutrino event.

• The Milky Way and thousands of neighboring galaxies are being pulled toward a mysterious gravitational anomaly known as the Great Attractor at a speed of 1.3 million miles per hour. • Located in the direction of the Centaurus constellation, this massive region of space exerts a powerful pull that overrides the general expansion of the universe in our local sector. • This phenomenon is significant because it challenges current understandings of cosmic movement and helps astronomers map the distribution of dark matter and large-scale structures.

• Astronomers using the James Webb Space Telescope discovered a massive galaxy that lacks rotation, an anomaly for an object formed less than 2 billion years after the Big Bang. • This lack of spin is a characteristic typically reserved for much older, evolved galaxies, contradicting current astronomical models of early universe development. • The discovery matters because it challenges existing theories regarding how galaxies grow and evolve during the early stages of the cosmos.

• Astronomers are observing a massive black hole actively tearing apart the galaxy NGC 1266, a lesser-known lenticular galaxy. • The process involves the black hole consuming surrounding matter, which triggers powerful outflows of gas and energy. • This event is significant because it allows researchers to study the "life stories" of lenticular galaxies and how supermassive black holes influence galactic evolution.

• The James Webb Space Telescope has discovered an ancient black hole that appears to have formed before its host galaxy, challenging existing astronomical models. • These findings stem from observations of "Little Red Dot" galaxies, which are extremely distant and ancient objects in the early universe. • The discovery represents a "paradigm shift" for scientists, as it forces a total revisiting of classical scenarios regarding how black holes and galaxies co-evolve.

• NASA’s James Webb Space Telescope has identified a massive black hole that appears to have formed before its host galaxy. • This discovery challenges the traditional scientific consensus that galaxies form first, with black holes later developing from the collapse of massive stars within them. • The finding is significant because it suggests a different evolutionary path for the early universe, where black holes may act as seeds for galaxy formation.

• NASA announced in December 2025 that construction of the Nancy Grace Roman Space Telescope is complete, with a scheduled launch by May 2027 or potentially as early as fall 2026. • During its five-year primary mission, the observatory aims to discover approximately 100,000 new transiting planets and create the largest catalog of rogue worlds in history. • This mission is significant because it will drastically expand the known exoplanet population and provide unprecedented data on planets drifting without host stars.

• Samsung launched its Galaxy Watch blood pressure feature for U.S. consumers, enabling wrist-based hypertension tracking without cuffs. • FDA-cleared technology uses optical sensors calibrated via user input, integrated into latest watch models. • Matters for 116 million U.S. adults with high blood pressure, improving remote monitoring and chronic disease management.

• Samsung began rolling out Quick Share with AirDrop interoperability on Galaxy S26 devices and additional models on March 24, 2026, enhancing cross-platform sharing for U.S. users. • The update improves file transfer compatibility between Android and iOS ecosystems. • This move strengthens Samsung's position in the competitive U.S. smartphone market.

• NASA's Astronomy Picture of the Day highlights NGC 1566, a grand design spiral galaxy located approximately 40 million light-years away in the constellation Dorado, known for its two prominent and graceful spiral arms traced by bright blue star clusters and red emission nebulas. • The galaxy's flaring center makes it one of the closest and brightest Seyfert galaxies, likely housing a central supermassive black hole affecting surrounding stars and gas, making it a prime target for Hubble Space Telescope observations studying star formation and supernovas. • NGC 1566 is among the most photogenic spiral galaxies in the universe, featuring a gorgeous face-on view and dark cosmic dust lanes that make it an ideal object for astronomical research and observation.

Figuring out what really counts as a galaxy could give us insights into dark matter and potentially shake up astrophysics, cosmology and particle physics, says columnist Chanda Prescod-Weinstein
