La galaxia lenticular NGC 4753 es un objeto realmente extraordinario. Su prominente y compleja red de bandas de polvo que se tuercen alrededor de su núcleo galáctico, define su “peculiar” clasificación y probablemente sea el resultado de una fusión galáctica con una cercana galaxia enana hace unos 1.300 millones de años atrás.

Experiments searching for dark matter or astrophysical neutrinos require low background detectors.
Eighteen years after NASA’s Stardust mission returned to Earth with the first samples from a known comet, the true nature of that icy object is coming into focus. Stardust collected material from Wild 2, a comet that likely formed beyond Neptune and currently orbits the sun between Mars and Jupiter. Painstaking analyses of the microscopic samples, recently described in the journal Geochemistry, have revealed a surprising truth about the comet’s origins and history, said Ryan Ogliore, an associate professor of physics in Arts & Sciences at Washington University in St.
RUDN University scientists have discovered that in weightlessness the contractile activity of smooth muscles in the hollow organs of the gastrointestinal tract is disrupted. New data must be taken into account when planning long-term space missions.
New research has cracked a vital process in the creation of a unique rock type from the Moon. The discovery explains its signature composition and very presence on the lunar surface at all, unravelling a mystery which has long eluded scientists.
A team of astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It’s a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve.The new planet was described in a new study published this week by The Astronomical Journal.
The Heineman Foundation, AIP, and American AAS are pleased to announce John E. Carlstrom as the winner of the 2024 Dannie Heineman Prize for Astrophysics.
Since the 1980s, the planetary system around the star Beta Pictoris has continued to fascinate scientists. Even after decades of study, it still holds surprises.
The Green Bank Telescope has discovered over 250 gaseous clouds being blasted out of the center of the Milky Way into interstellar space. A decade ago, astronomers weren’t aware of this phenomenon. It took years of observations, and some surprising finds, to produce this latest result.
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed.
Astronomers using Hubble have found the location of the farthest and brightest fast radio burst ever detected. It exploded within a collection of merging galaxies that existed when the universe was only 5 billion years old.
Astronomers using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) that may display possible aurorae, like the familiar Northern Lights on our world. This is an unexpected mystery because the brown dwarf, known as W1935, is an isolated object in space, with no nearby star to create an aurora.
In the culmination of a decade’s worth of effort, the DES collaboration of scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova survey. While consistent with the current standard cosmological model, the results do not rule out a more complex theory that the density of dark energy in the universe could have varied over time.
Using the DOE-fabricated Dark Energy Camera, mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, the Dark Energy Survey has obtained the largest supernova sample ever using a single telescope.

Their concentrations vary with height in the thick and hostile Venusian atmosphere. But until now they have been unable to identify the missing component that would explain the clouds’ patches and streaks, only visible in the UV range.
