Webb’s image of the enormous stellar jet in Sh2-284 provides evidence that protostellar jets scale with the mass of their parent stars—the more massive the stellar engine driving the plasma, the larger the resulting jet.

Vatican City, Dec 1, 2025 / 13:44 pm (CNA).
Pope Leo XIV on Monday appointed Bishop Mario Avilés as the new bishop of Corpus Christi, selecting the Mexican-born Oratorian to lead the south Texas diocese.
Avilés, 56, who has served as auxiliary bishop of Brownsville, Texas, since February 2018, will succeed Bishop Michael Mulvey, 76. Mulvey has led the Diocese of Corpus Christi since 2010.
“We welcome Bishop-designate Avilés with open hearts and deep prayer,” Mulvey said in a statement after the Vatican announcement on Dec. 1.
As the ninth bishop of Corpus Christi, Avilés will take responsibility for the spiritual leadership of more than 200,000 Catholics across a 12-county region in south Texas.
“The Diocese of Brownsville will greatly miss Bishop Mario’s wise counsel and good judgment, his joyful presence in our parish communities, and his administrative skills in the service of our diocesan offices and Catholic schools. Yet at the same time we share in the special joy of the Diocese of Corpus Christi at the news of Bishop Mario’s appointment,” Brownsville Bishop Daniel Flores said in a statement.
Avilés was born on Sept. 16, 1969, in Mexico City. In 1986, he joined the Congregation of the Oratory of St. Philip Neri, a pontifical society of apostolic life composed of priests and lay brothers founded in 1575, which now has more than 70 oratories worldwide.
He studied for the priesthood in Mexico City before continuing his education in Rome, earning bachelor’s degrees in philosophy and sacred theology at the Pontifical Athenaeum Regina Apostolorum. He also holds a master’s degree in education administration and supervision and is a certified teacher in the state of Texas.
At the age of 28, Avilés was ordained a priest in the Basilica of Our Lady of San Juan del Valle National Shrine in San Juan, Texas. He became parochial vicar at St. Jude Thaddeus Church in Pharr and worked in the Pharr Oratory Schools as a governance board member, teacher, principal, and rector. He also served as vicar, secretary, treasurer, and novice master for the Oratorian congregation.
From 2000 to 2012, he served on the Permanent Deputation of the Confederation of the Oratory of St. Philip Neri for Latin America. At the congregation’s 2012 General Congress, he was elected procurator general of the confederation, a Rome-based role representing Oratorian communities to the Holy See. He speaks Spanish, English, and Italian.
Avilés’ episcopal motto is “Caritas Dei diffusa est in cordibus nostris,” meaning “The love of God has been poured out into our hearts,” a reference to Romans 5:5 and the introit of the Mass for the feast of St. Philip Neri. His crest includes red roses honoring Our Lady of Guadalupe and his Mexican heritage as well as three gold stars drawn from the Neri family crest, symbolizing his long affiliation with the oratory.
“I ask all the faithful of the Diocese of Brownsville to pray for Bishop Mario as he prepares to take up his new mission of service in Corpus Christi,” Flores said. “May God bless Bishop Mario Avilés and may the maternal care of the blessed and ever-immaculate Virgin Mary accompany him always.”

This image shows two massive galaxy clusters. The vast number of galaxies and foreground stars in the image were captured by NASA’s James Webb Space Telescope in near-infrared light. Glowing, hot X-rays captured by NASA’s Chandra X-ray Observatory appear in pink. The blue represents the dark matter, which was precisely mapped by researchers with Webb’s detailed imaging.

Westerlund 1 is the biggest and closest “super” star cluster to Earth. Data from Chandra and other telescopes are helping astronomers delve deeper into this galactic factory where stars are vigorously being produced. Observations from Chandra have uncovered thousands of individual stars pumping out X-ray emission into the cluster.

A close-in image of a protoplanetary disc HH 30 around a newly formed star produced by NASA/ESA/CSA James Webb Space Telescope. It is surrounded by jets and a disc wind, and is located in the dark cloud LDN 1551 in the Taurus Molecular Cloud. Herbig-Haro objects are small nebulae found in star formation regions, marking the locations where gas outflowing from young stars is heated into luminescence by shockwaves. HH 30 is an example of where this outflowing gas takes the form of a narrow jet. The source star is located on one end of the jet, hidden behind an edge-on protoplanetary disc that the star is illuminating.

The 25th anniversary logo is visible in the cupola of the space station in this July 17, 2025, image. The central astronaut figure is representative of all those who have lived and worked aboard the station during the 25 years of continuous human presence. In the dark sky of space surrounding the astronaut are 15 stars, which symbolize the 15 partner nations that support the orbiting laboratory.

The bright variable star V 372 Orionis takes center stage in this image from the NASA/ESA Hubble Space Telescope, which has also captured a smaller companion star in the upper left of this image. Both stars lie in the Orion Nebula, a colossal region of star formation roughly 1450 light years from Earth.

NASA’s James Webb Space Telescope recently imaged the Sombrero Galaxy with its NIRCam (Near-Infrared Camera), which shows dust from the galaxy’s outer ring blocking stellar light from stars within the galaxy. In the central region of the galaxy, the roughly 2,000 globular clusters, or collections of hundreds of thousands of old stars held together by gravity, glow in the near-infrared. The Sombrero Galaxy is around 30 million light-years from Earth in the constellation Virgo. From Earth, we see this galaxy nearly “edge-on,” or from the side.

This new image showcases the dazzling young star cluster NGC 346. Although both the James Webb Space Telescope and the Hubble Space Telescope have released images of NGC 346 previously, this image includes new data and is the first to combine Hubble observations made at infrared, optical, and ultraviolet wavelengths into an intricately detailed view of this vibrant star-forming factory.

Shimmering ejections emitted by two actively forming stars make up Lynds 483 (L483). High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows incredible new detail and structure within these lobes, including asymmetrical lines that appear to run into one another. L483 is 650 light-years away in the constellation Serpens.
