Small rocky planet detected in orbit about nearby Barnard’s star

While this planet, orbiting very close to Barnard’s star, has a surface temperature too high to be suitable for life, the researchers found what they called “strong hints” of three other planets around Barnard’s star that might be better candidates.

Barnard’s star is a red dwarf, the smallest type of regular star and much smaller and less luminous than our sun. At about 6 light years away, it is the closest single star – one not orbiting with other stars – to our solar system. It is, in cosmic terms, in our neighborhood.

Because of this, scientists eager to study nearby potentially habitable worlds are excited by the discovery of the first confirmed planet orbiting Barnard’s star, a rocky one with a mass about 40% that of Earth, Reuters reported.

While this planet, orbiting very close to Barnard’s star, has a surface temperature too high to be suitable for life, the researchers found what they called “strong hints” of three other planets around Barnard’s star that might be better candidates.

The confirmed planet, called Barnard b, has a predicted diameter about three-quarters that of Earth, so about 6,000 miles (9,700 km).

“It is one of the least massive planets ever found,” beyond our solar system, said astronomer Jonay González Hernández of the Instituto de Astrofísica de Canarias in Tenerife, Spain, lead author of the study published this week in the journal Astronomy & Astrophysics, opens new tab.

Among planets in our solar system, only Mars and Mercury are smaller.

Barnard b, with a surface temperature around 275 degrees Fahrenheit (125 degrees Celsius), orbits Barnard’s star in just three Earth days at a distance 20 times closer than our solar system’s innermost planet Mercury is to the sun.

Planets beyond the solar system are called exoplanets. Scientists searching for exoplanets that possibly could harbor life look at those residing in the “habitable zone” around a star, where it is not too hot and not too cold, and liquid water can exist on the planetary surface.

The researchers used an instrument called ESPRESSO on the European Southern Observatory’s Chile-based Very Large Telescope to detect this planet. The three other potential planets orbiting Barnard’s star all apparently are rocky and smaller than Earth, ranging from 20-30% of Earth’s mass. The hope is that at least one of these may be in the vicinity of the habitable zone.

If confirmed, this would be the only known star with a multi-planet system entirely comprised of planets smaller than Earth.

Barnard’s star, in the constellation Ophiuchus, has a mass about 16% of the sun’s, a diameter 19% of it and is far less hot. It also is estimated to be more than twice as old as the sun.

“Being so cold and small, it is quite faint, making its habitable zone much closer to the star than in the case of the sun,” said Instituto de Astrofísica de Canarias astronomer and study co-author Alejandro Suárez Mascareño. “It also is a very quiet star. While some red dwarfs have been found to flare very frequently, Barnard’s star doesn’t do it.”

The closer that exoplanets are to us, the easier they are to study. It is easier to detect low-mass rocky planets orbiting red dwarfs, the most common type of star in our Milky Way galaxy, than around larger stars.

Only the three stars in the Alpha Centauri system, about 4 light-years away, are closer to our solar system than Barnard’s star. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Two exoplanets have been detected in the Alpha Centauri system, both orbiting the red dwarf Proxima Centauri. One has a mass about equal to Earth’s. The other is about 25% Earth’s mass.

In science fiction, light speed travel is commonplace. In reality, it is far beyond human capabilities, though research projects such as Breakthrough Starshot are exploring the feasibility of interstellar travel. Barnard’s star and Alpha Centauri might be on wish lists of future destinations.

“While they are very close in astronomical terms, they are out of reach for any kind of human technology. However, if projects such as the Breakthrough Starshot are successful, it is likely that these will be some of the first targets,” Mascareño said.

Pakistan’s actions target militants, not religious sites: Khawaja Asif

He rejected claims equating these operations with India’s alleged strikes on mosques and religious seminaries in Bahawalpur and Muridke, stressing that Pakistan does not target religious or civilian sites.

Pakistan’s Defence Minister Khawaja Muhammad Asif has dismissed comparisons between Pakistan’s counterterrorism operations along the disputed Durand Line and what he described as India’s attacks on religious sites, saying such parallels are “entirely wrong and inappropriate.”

In a statement issued Tuesday, Asif said Pakistan’s military actions are strictly aimed at verified camps belonging to Tehreek-e-Taliban Pakistan (TTP) militants operating from Afghanistan. He rejected claims equating these operations with India’s alleged strikes on mosques and religious seminaries in Bahawalpur and Muridke, stressing that Pakistan does not target religious or civilian sites.

The defence minister said the international community, including the United Nations, has repeatedly expressed concern over the threat of terrorism they claim is originating from Afghanistan. He said these concerns are reinforced by continued militant infiltration and attacks inside Pakistan, which, according to him, are carried out by armed groups entering from Afghan territory.

Referring to India’s allegations surrounding the Pahalgam incident, Asif said New Delhi has failed to present credible or verifiable evidence to support its claims. He added that Pakistan had offered to cooperate with an independent and impartial investigation, an offer that India declined.

Asif further said a recent United Nations report had described India’s actions as illegal and based on unsubstantiated claims, while affirming that Pakistan’s response was justified under international law. He said Pakistan has already addressed and clarified allegations regarding India, what he termed proxy extremist elements, and their alleged supporters.

Reiterating Pakistan’s stance, the defence minister said the country remains vigilant and determined to protect its sovereignty and national security. He emphasized that Pakistan will continue its counterterrorism efforts and will challenge what he described as baseless accusations and hostile narratives at all international forums.

Meanwhile, the Islamic Emirate of Afghanistan (IEA) has consistently rejected Pakistan’s accusations, maintaining that Afghanistan does not allow any group to operate from its soil. Afghan authorities have repeatedly stated that Pakistan’s security challenges are an internal matter and should be addressed domestically.

Germany conducts first deportation to Syria in a decade

The deportation marks a historic shift in German migration policy and signals the government’s determination to enforce stricter measures against convicted foreign nationals.

deportations from germany

Germany has carried out its first deportation to Syria since the outbreak of the country’s civil war in 2011, sending a convicted Syrian national back to Damascus on a scheduled commercial flight.

The 37-year-old man, who had served a prison sentence in North Rhine-Westphalia for aggravated robbery, bodily harm, and extortion, was escorted by federal police to the Syrian capital, where he was handed over to local authorities on Tuesday, December 23.

The Federal Interior Ministry confirmed the deportation, which coincided with another removal of an individual to Afghanistan. The ministry said it had reached agreements with both Damascus and Kabul authorities to facilitate “regular” deportations of serious offenders and individuals considered security risks in the future.

The Afghan national had been imprisoned in Bavaria, including for intentional bodily harm. The ministry said this marked the second deportation of an Afghan criminal within a week.

“Criminals must leave our country. We stand for control, consequence, and zero tolerance towards offenders and threats,” said Interior Minister Alexander Dobrindt (CSU), emphasizing that the move reflects Germany’s commitment to law and order.

Dobrindt further justified the policy by highlighting the strain on local municipalities, which have faced challenges accommodating foreign nationals serving prison sentences. “We have reached the breaking point for a long time, and the overload in the municipalities is visible,” he said.

The deportation follows months of diplomatic negotiations after the fall of Bashar al-Assad’s regime in December 2024, which ended a 14-year civil war. The change prompted Germany to reassess its long-standing ban on returns to Syria.

The current coalition government, formed by CDU/CSU and SPD, explicitly committed in its agreement to resume deportations to Syria and Afghanistan, targeting criminals and “Gefährder” — individuals considered potential security threats. Chancellor Friedrich Merz has been a vocal supporter of the policy, meeting with Syria’s transitional president Ahmed al-Sharaa to discuss mechanisms for further returns.

The move carries symbolic weight amid heightened public concern over migration, with roughly one million Syrians currently residing in Germany, many of whom arrived during the 2015-2016 refugee influx under former Chancellor Angela Merkel.

While the German government asserts that the Syrian conflict is over, human rights organizations continue to caution against deportations, citing lingering instability, ongoing reconstruction challenges, and potential security risks for returnees.

The deportation marks a historic shift in German migration policy and signals the government’s determination to enforce stricter measures against convicted foreign nationals.
