On 19 March 2025, our Euclid mission released its first batch of survey data, revealing an astonishing view of the cosmic web.
With just one scan of its deep fields, Euclid has already detected 26 million galaxies, some as far as 10.5 billion light-years away! This is just a preview of what’s to come, as Euclid will continue mapping the Universe in unprecedented detail.
What’s in this first release? – Three vast mosaics covering 63 square degrees of the sky – A catalogue of 380 000 galaxies, classified with AI + citizen scientists – 500 new gravitational lens candidates, almost all never seen before – The first hints of Euclid’s full cosmic atlas, which will eventually cover one-third of the sky
This data is a huge leap forward in understanding how galaxies are distributed across the Universe and how dark matter and dark energy shape the cosmos.
Over the next six years, Euclid will revisit these deep fields 30 to 52 times, uncovering billions of galaxies and pushing the astrophysics’ boundaries.

Unii cercetători propun că această direcție preferențială ar putea fi legată de condițiile din momentul Big Bang-ului, când materia ar fi avut deja o direcție de rotație imprimată, similar cu formarea unui sistem solar sau a unui vârtej. Poplawski, un fizician polonez, susține o teorie bazată pe extinderea teoriei relativității generale a lui Einstein, numită teoria Einstein-Cartan. Aceasta introduce conceptul de torsiune a spațiului, care ar explica formarea unui univers nou din interiorul unei găuri negre.
Potrivit acestei teorii, în loc să se formeze o singularitate în centrul găurii negre, ar apărea un portal asemănător unei găuri albe, ceea ce ar da naștere unui nou univers. Poplawski sugerează că universul nostru ar fi fost creat astfel, iar materia din acest nou univers ar proveni dintr-o gaură neagră existentă într-un alt univers. De asemenea, teoria lui sugerează că universul ar trebui să fie euclidian, iar raza universului observabil ar fi similară cu cea a unei găuri negre, având în vedere masa întregului univers.
Aceste idei sunt susținute de calcule care prezic o direcție preferențială de rotație a galaxiilor, iar măsurătorile recente din cadrul telescopului James Webb oferă dovezi care par să sprijine aceste teorii. Această descoperire deschide noi perspective asupra originii și structurii universului nostru.”
NASA’s SPHEREx and PUNCH missions are set to launch together, with one mission aiming to answer big-picture questions about our universe and the other seeking a better understanding of our Sun.
SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) is an infrared space telescope designed to map the entire sky like none before it. SPHEREx will study the origins of the universe, galaxies, and the ingredients for life in our galaxy.
PUNCH (Polarimeter to Unify the Corona and Heliosphere) is a constellation of four small satellites dedicated to studying the Sun’s outer atmosphere, the solar corona, and how it extends into space to form the solar wind. Understanding these processes is critical to predicting space weather and its impact on Earth’s magnetic field.
Together, SPHEREx and PUNCH demonstrate NASA’s commitment to uncovering the fundamental forces that shape our universe and our own star.
This video takes the viewer on a journey through space to the Rho Ophiuchi cloud complex.
From our cosmic backyard in the Solar System to distant galaxies near the dawn of time, the NASA/ESA/CSA James Webb Space Telescope has delivered on its promise of revealing the Universe like never before in its first year of science operations. To celebrate the completion of a successful first year, a new Webb image has been released of a small star-forming region in the Rho Ophiuchi cloud complex. While the region is relatively quiet, its proximity at 390 light-years makes for a highly detailed close-up, with no foreground stars in the intervening space.

This video takes the viewer on a journey through space to the peculiar galaxy NGC 3256.
This distorted galaxy is the wreckage of a head-on collision between two spiral galaxies which likely occurred 500 million years ago, and it is studded with clumps of young stars which were formed as gas and dust from the two galaxies collided.

This video takes the viewers on a journey to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image. NGC 5068 lies around 17 million light-years from Earth in the constellation Virgo.
With its ability to peer through the gas and dust enshrouding newborn stars, the NASA/ESA/CSA James Webb Space Telescope is the perfect telescope to explore the processes governing star formation. Stars and planetary systems are born amongst swirling clouds of gas and dust that are opaque to visible-light observatories like Hubble or the VLT. The keen vision at infrared wavelengths of two of Webb’s instruments — MIRI and NIRCam — allowed astronomers to see right through the gargantuan clouds of dust in NGC 5068 and capture the processes of star formation as they happened. This image combines the capabilities of these two instruments, providing a truly unique look at the composition of NGC 5068.

Two of the most distant galaxies seen to date have been captured by Webb in the outer regions of the giant galaxy cluster Abell 2744. The galaxies are not inside the cluster, but many billions of light-years behind it.
One of the galaxies existed only 450 million years after the Big Bang while the other one existed 350 million years after the Big Bang.
Both galaxies are seen really close in time to the Big Bang which occurred 13.8 billion years ago.

Thousands of never-before-seen young stars are spotted in a stellar nursery called 30 Doradus, captured by the @NASA/ESA/@Canadian Space Agency James Webb Space Telescope. Nicknamed the Tarantula Nebula for the appearance of its dusty filaments in previous telescope images, the nebula has long been a favourite for astronomers studying star formation. In addition to young stars, Webb reveals distant background galaxies, as well as the detailed structure and composition of the nebula’s gas and dust.

NASA revealed the first five full-color images and spectrographic data from the world’s most powerful space telescope, the James Webb Space Telescope, a partnership with ESA (European Space Agency), and CSA (Canadian Space Agency). The world got its first look at the full capabilities of the mission at a live event streamed from the agency’s Goddard Space Flight Center in Greenbelt, Maryland, on July 12, 2022.
The event showcased these targets: – Carina Nebula: A landscape speckled with glittering stars and cosmic cliffs – Stephan’s Quintet: An enormous mosaic with a visual grouping of five galaxies – Southern Ring Nebula: A nebula with rings of gas and dust for thousands of years in all directions – WASP 96-b: A distinct signature of water in the atmosphere of an exoplanet orbiting a distant Sun-like star – SMACS 0723: The deepest and sharpest infrared image of the distant universe to date
The full set of the telescope’s first full-color images and spectroscopic data are available at: https://nasa.gov/webbfirstimages
Each year, the NASA/ESA Hubble Space Telescope dedicates a small portion of its precious observing time to taking a special anniversary image, showcasing particularly beautiful and meaningful objects. These images continue to challenge scientists with exciting new surprises and to enthral the public with ever more evocative observations.
To celebrate Hubble’s 30th anniversary, let’s look back at the beauty and science behind each of the anniversary images unveiled as of 2005. In this video, we will also feature the very special 2020 Hubble Space Telescope 30th anniversary image.

The second data release of ESA’s Gaia mission has produced an extraordinary catalogue of over one and a half billion stars in our galaxy. Based on observations between July 2014 to May 2016, it includes the most accurate information yet on the positions, brightness, distance, motion, colour and temperature of stars in the Milky Way as well as information on asteroids and quasars.
Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since “accelerated” to faster than the speed of light. You might go further and say that there are more distant galaxies that we can’t see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn’t from doppler and this “acceleration” of the expanding universe isn’t actually causing a true increase in velocity.
Sometimes astronomers do say there is a faster than light “recession speed” by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that’s misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.
