1/3 The imagery of flowers isn't rare in the sky. Here's NGC 7023, the Iris Nebula, a stupendous and bright reflection nebula lying in Cepheus, 1,300 ly away. The bright blue portion is 6 ly across. Credit and info➡️go.nasa.gov/3F1emJl #scritturebrevi #VentagliDiParole

The JWST has turned the spotlight on the Sombrero Galaxy (M104), famous for its shape that resembles a Mexican hat. After a mid-infrared image in 2024, Webb has captured a new image in near-infrared. Located 30 Mly away, M104 continues to reveal its secrets thanks to new images

This nice image provides an overview of the 25 brightest stars in the night sky. It shows them in true color, highlighting their beauty and diversity. Many of these stars have names derived from Arabic, Greek, Latin, or Egyptian traditions, reflecting their central role in

A new super interesting study has mapped stellar remnants, such as black holes (BHs), neutron stars (NSs), and white dwarfs (WDs) in about 10,000 galaxies observed by the MaNGA/SDSS-IV survey. When a massive star runs out of fuel, it can go supernova, leaving behind a black hole

Happy June Solstice! It happens in an instant for everyone on our planet. Precisely, the June Solstice 2025 will happen today, 21 June, at 02:42 UTC. The June Solstice marks the astronomical beginning of summer in the Northern Hemisphere and winter in the Southern Hemisphere.

#OTD in 1633, the Holy Office in Rome issued a sentence condemning Galileo Galilei, who was found "vehemently suspected of heresy": "that is, of having held and believed a false doctrine contrary to the Holy and Divine Scriptures, that the sun is the center of the earth and that

The first images from the NSF–DOE Vera C. Rubin Observatory (NSF-DOE Rubin Observatory) are here, and they are breathtaking! This spectacular image shows only a small corner of total view of the Virgo Cluster, 55 Mly away. Visible are two notable spiral galaxies (NGC 4411b, left; NCG 4411a,

#OTD in 1903, Marie Skłodowska Curie defended her PhD thesis. She, after thousands of crystallizations, finally had isolated 1 decigram of almost pure radium chloride and determined radium’s atomic weight as 225. The findings were presented in her PhD thesis. The committee

Since 1912, Andromeda (M31) has been known to be approaching the Milky Way (MW). In 2012, Hubble data suggested an almost certain collision within 4-5 billion years, but a recent study has some surprises in store. Using super-precise data from the Hubble and Gaia telescopes,

#OTD in 1906, the pioneering physicist Maria Goeppert-Mayer was born. She entered history as the nuclear shell model theorist and as the 2nd woman to win the Nobel Prize in Physics, after Marie Curie. M. G. Mayer and J. H. D. Jensen shared one half of the Nobel Prize. The other

At a distance of about 2.5 Mly, the Andromeda galaxy (M31) is our closest cosmic neighbor, a perfect laboratory for exploring the Universe. This spectacular new image, created by combining data from telescopes Chandra, XMM-Newton, GALEX, Spitzer, and others, gives us an

"The soul is the mirror of an indestructible universe." — Gottfried W. Leibniz, 'Monadology'. A great mathematician, a great philosopher, and much more, Leibniz was born #OTD in 1646. One of the greatest exponents of Western thought, his intellectual application to almost all

This fascinating image shows the path traced by a rare total solar eclipse over ESO’s La Silla Observatory (Chile) on 2 July 2019. The previous total solar eclipse visible from La Silla occurred at the end of the 16th century, the next will not be until the year 2231. Total

A very recent study uses the sharp images of #JWST to provide the most detailed mass reconstruction of the *Bullet Cluster (1E 0657-56) to date, an extraordinary system consisting of two colliding galaxy clusters. Imagine a colossal cosmic collision, powerful enough to separate

5th July 1687 is often cited as the publication date of Isaac Newton’s “Philosophiæ Naturalis Principia Mathematica,” one of the masterpieces of modern science. But is it really so? This date comes from a letter (dated 5th July 1687) from Edmond Halley, who financed and oversaw

My book with Jack Szostak "Is Earth Exceptional?" now appeared also in Italy and Brazil. It is interesting how the three editions have very different covers.

The European Space Agency (ESA) announced, a few days ago, the discovery of a rare interstellar object: the comet 3I/ATLAS, the third object of this type ever identified, after 1I/ʻOumuamua (2017) and 2I/Borisov (2019). Detected on July 1, 2025 by the ATLAS telescope in Río

A recent article from the Royal Astronomical Society suggests that Earth and the Milky Way may be sitting at the centre of a vast “cosmic void” with a lower-than-average density, which could explain the so-called “Hubble tension”. This theory was presented at the National Astronomy Meeting
