NASA’s Webb catches Tarantula Nebula

A stellar nursery nicknamed the Tarantula Nebula has been captured in crisp detail by NASA’s Webb telescope, revealing hitherto unseen features that deepen scientific understanding, the agency said Tuesday.
Officially known as 30 Doradus, the region of space is characterized by its dusty filaments that resemble the legs of a hairy spider, and has long been a favorite for astronomers interested in star formation.
Thousands of young stars, distant background galaxies, and the detailed structure of the nebula’s gas and dust structures were viewable for the first time thanks to Webb’s high resolution infrared instruments.
Webb operates primarily in the infrared spectrum, because light from objects in the distant cosmos has been stretched into this wavelength over the course of the universe’s expansion.
The telescope’s primary imager, Near-Infrared Camera (NIRCam), found the cavity in the center of the nebula was hollowed out by radiation carried on stellar winds emanating from a cluster of massive young stars, which appear as pale blue dots.
Webb’s Near-Infrared Spectrograph (NIRSpec), which analyzes light patterns to determine the composition of objects, caught one young star in the act of shedding a cloud of dust from around itself.
The same star was previously thought to be at a later stage of formation, already well on the way to clearing its dusty bubble.
The region was also imaged using the Mid-infrared Instrument (MIRI), which uses longer wavelengths of infrared to pierce through dust grains that absorb or scatter shorter wavelengths.
This faded the hot stars and clarified the cooler regions, revealing never-before-seen points of light within the stellar nursery, which indicate protostars that are still gaining mass.
Astronomic interest in the Tarantula Nebula stems from its similar chemical composition to gigantic star-forming regions observed a few billion years after the Big Bang, a period called the “cosmic noon” when star formation peaked.
At just 161,000 light-years away, Tarantula is a readily viewable example of this flourishing period of cosmic creation.
Webb should also provide scientists the opportunity to gaze at distant galaxies from the actual era of cosmic noon, and compare it to observations of Tarantula, to understand similarities and differences.
Operational since July, Webb is the most powerful space telescope ever built, with astronomers confident it will herald a new era of discovery.

María Corina Machado: “Venezuela is closer than ever to regaining freedom”
Venezuelan opposition leader and 2025 Nobel Peace Prize laureate María Corina Machado declared on Friday that Venezuela is facing “the most decisive moment in its contemporary history” and that the country is “closer than ever to regaining freedom and democracy.”
Her remarks were delivered via video message during the 81st General Assembly of the Inter American Press Association (IAPA), held in Punta Cana, Dominican Republic.
Machado emphasized that the situation in Venezuela remains “extremely serious” due to censorship and repression imposed by Nicolás Maduro’s regime, particularly in a global context where “society is built on information.”
She warned that authoritarian governments manipulate public opinion through “psychological warfare” and disinformation, while shutting down media outlets and persecuting journalists.
“The only way to topple these regimes is through the constant, relentless, and unrestricted preaching of the truth. It is absolutely true that the truth will set us free,” she stated.

Millions to join “No Kings” march in U.S. amid Trump’s growing authoritarian backlash
Millions of Americans are set to take to the streets this Saturday in more than 2,500 cities across the United States for the second edition of the “No Kings” march, a massive protest organized by progressive groups and activists against what they describe as the authoritarian direction of President Donald Trump’s second administration.
The demonstration, expected to be the largest since Trump’s return to power, comes amid a federal government shutdown, further heightening political tensions in Washington.
From the White House, press secretary Abigail Jackson dismissed the event with a brief “Who cares?”, while senior Republican leaders labeled the march as an act of “hate against America.”
House Speaker Mike Johnson accused Democrats of blocking negotiations to reopen the government and claimed they were “unable to stand up to their raging base.” He also linked the protests to “supporters of Hamas and the Antifa terrorist group.”
President Donald Trump, in an interview with Fox News, blamed Senate Democratic leader Chuck Schumer for the legislative deadlock.
“He’s got nothing else left to do. Everyone’s hitting him hard,” Trump said.
The organizers — a coalition of Democratic leaders and more than 200 civil society and labor groups — argue that the Republican refusal to reopen the government is a clear symptom of the authoritarianism they seek to denounce.
The main rally will take place in Washington, D.C., which has been under heightened National Guard surveillance for weeks, officially to control rising crime. However, organizers contend the deployment is aimed at intimidating and silencing dissent.
Protesters have been urged to wear yellow, a reference to the 2019 pro-democracy movement in Hong Kong.
“With this color, we align ourselves with a historical context and remind the world that power must come from the people, not from crowns,” organizers stated on their website.
In addition to the capital, large marches are scheduled in New York, San Francisco, Boston, Atlanta, Chicago, Kansas City, and Honolulu, as well as abroad in London, Paris, Frankfurt, and several Spanish cities — Madrid (Puerta del Sol), Barcelona (Plaça Sant Jaume), Seville (Plaza Nueva), and Málaga (Plaza de la Marina).
During the first edition, held in June, the movement gathered around five million people, a figure organizers expect to surpass this weekend.

Petro expresses concern over fatal shooting during mass protests in Lima
Colombian President Gustavo Petro voiced his “concern” on Thursday over recent events in Peru, following the death of a protester reportedly shot during a massive demonstration in Lima against the government and Congress.
“I must express my concern over the events in Peru. A young artist has been killed in citizens’ protests,” Petro wrote on X (formerly Twitter).
The Colombian leader also noted that in Peru, “a popularly elected president remains imprisoned without conviction,” referring to Pedro Castillo, who led the country from July 2021 to December 2022 until he was removed by Congress following a failed attempted coup.
“This is a blatant violation of the American Convention on Human Rights,” Petro stated, adding, “I hope Peru seeks social and political dialogue to legitimize its public institutions.”
On Wednesday, Peru experienced widespread protests in several cities, with the largest demonstration in Lima in recent years, driven by citizens’ concerns over corruption and public insecurity.
During the capital’s mobilization, the Ombudsman’s Office confirmed the death of Eduardo Ruiz, 32, and reported clashes that left over 100 injured, including 78 police officers and 24 protesters, as well as ten arrests.
The Attorney General’s Office, investigating Ruiz’s death “in the context of serious human rights violations,” confirmed that the protester was shot.
