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.

Afghanistan highlights water diplomacy at Tashkent ministerial forum
Speaking at the event, Mujeeb-ur-Rahman Omar Akhundzada emphasized the need for equitable water distribution between Afghanistan and Central Asian nations.
Afghanistan has underscored the importance of water diplomacy and regional cooperation during a ministerial forum held in Tashkent, the capital of Uzbekistan.
The country’s Deputy Minister for Water at the Ministry of Water and Energy participated in the “Water Week” forum, where he called for stronger collaboration among regional partners in managing shared water resources.
Speaking at the event, Mujeeb-ur-Rahman Omar Akhundzada emphasized the need for equitable water distribution between Afghanistan and Central Asian nations. He also highlighted the importance of enhancing water diplomacy and adopting modern technologies to improve water management systems.
Akhundzada further stressed the urgency of joint regional efforts to tackle the effects of climate change and prevent environmental degradation along the Amu Darya River. He reaffirmed Afghanistan’s commitment to respecting the water rights of neighboring countries while strengthening its domestic water infrastructure.
On the sidelines of the forum, Akhundzada met with Shavkat Khamrayev to discuss expanding bilateral cooperation in water management between Afghanistan and Uzbekistan.
Afghanistan’s participation in the forum is seen as a significant step toward boosting its engagement in regional and international water discussions, potentially paving the way for deeper cooperation across Central Asia.

UN experts call for lasting ceasefire as Afghan–Pakistan violence escalates
United Nations human rights experts have called for an urgent and lasting ceasefire between Afghanistan and Pakistan following a sharp escalation in cross-Durand Line fighting that has caused widespread civilian suffering.
In a statement issued Tuesday, the experts warned that renewed hostilities since late February have resulted in at least 289 civilian casualties in Afghanistan, including 76 deaths and 213 injuries.
More than 115,000 people have reportedly been displaced, with extensive damage to homes, hospitals, markets, and displacement camps. The violence has also forced school closures and disrupted trade in affected regions.
The latest unrest follows the collapse of a ceasefire agreement reached in October 2025. Fighting reignited after Pakistani airstrikes targeted positions linked to Tehreek-e-Taliban Pakistan (TTP), prompting retaliatory attacks along the disputed Durand Line.
Concerns over civilian harm
UN experts strongly condemned a March 16 airstrike by Pakistan that struck a drug rehabilitation centre in Kabul, reportedly causing mass civilian casualties. They also raised concerns over attacks inside Pakistan attributed to TTP groups, which have also resulted in civilian harm.
“Both sides must commit to a permanent ceasefire, address the root causes of the conflict, and ensure accountability for violations of international law,” the experts said.
They emphasized the obligation of all parties to adhere to international human rights and humanitarian law, particularly the protection of civilians and civilian infrastructure. The experts also called for independent, transparent investigations into alleged violations.
Disputed claims and rising tensions
Pakistan has defended its military operations, saying they were carried out in response to alleged support by Afghan authorities for the TTP, a group under UN sanctions. Authorities in Afghanistan have rejected the claims denying any involvement.
UN experts noted that Pakistan has not publicly presented credible evidence linking TTP attacks directly to Afghan authorities.
They further stressed that under international law, states must not support or tolerate armed groups conducting cross-Durand Line attacks and must resolve disputes through peaceful means.
Calls for dialogue
The United Nations experts confirmed they have been in contact with officials from both countries, urging restraint, de-escalation, and a return to dialogue.
With tensions continuing to rise, they warned that ongoing violence risks further civilian casualties and deepening instability unless immediate steps are taken toward a sustainable peace agreement.

Doyle returns to US after release by Islamic Emirate in Afghanistan
An American citizen, Dennis Coyle, arrived in the United States on Wednesday after being released by the Islamic Emirate in Afghanistan, marking a significant development amid ongoing diplomatic efforts between Washington and Kabul.
U.S. officials confirmed that Coyle arrived on American soil, landing at a major international airport in Texas, where he was met by close family members, including immediate relatives who had long campaigned for his release. Emotional scenes were reported as family members welcomed him home after an extended period in detention.
While authorities have not disclosed full details surrounding his release, officials indicated that quiet diplomatic engagement played a key role in securing his freedom. The case had drawn attention from human rights groups and policymakers, who had called for his release on humanitarian grounds.
Sources familiar with the situation said Coyle is expected to undergo medical evaluations following his return, a standard procedure for detainees released after prolonged confinement. Family members have requested privacy as he begins the process of reintegration.
Coyle’s release comes at a time of complex relations between the United States and the Islamic Emirate, with limited formal diplomatic ties but ongoing indirect engagement on humanitarian and security issues.
Analysts say the development could signal potential openings for further negotiations, particularly regarding other detainees still held in Afghanistan and abroad. It also follows renewed calls by families of other prisoners—including Afghan nationals held overseas—for similar humanitarian consideration.
U.S. officials have not confirmed whether additional releases are under discussion, but emphasized their continued commitment to securing the return of all American citizens detained abroad.
For now, Coyle’s return marks a positive development, offering hope to other families awaiting similar outcomes.
