Australian telescope finds new galaxies at record speed
A powerful new telescope in the Australian outback has mapped vast areas of the universe in record-breaking time, revealing a million new galaxies and opening the way to new discoveries, the country’s national science agency reported this week.
The radio telescope, dubbed the Australian Square Kilometre Array Pathfinder (ASKAP), was able to map about three million galaxies in just 300 hours, Reuters reported.
Comparable surveys of the sky have taken as long as 10 years.
“It’s really a game changer,” said astronomer David McConnell, who led the Commonwealth Scientific and Industrial Research Organisation (CSIRO) study of the southern sky at the Murchison Radioastronomy Observatory in Western Australia.
Reuters reported that what makes this telescope unique is its wide field of view, using receivers designed by CSIRO, which allow it to take panoramic pictures of the sky in sharper detail than before.
The telescope only needed to combine 903 images to map the sky, compared with other all-sky radio surveys that require tens of thousands of images.
“It is more sensitive than previous surveys that have covered the whole sky like this, so we do see more objects than have been seen in the past,” McConnell told Reuters.
Having a telescope that can survey the sky in a few weeks or months means the process can be repeated again and again in a relatively short space of time, allowing astronomers to systematically spot and track changes.
“Even with this first pass we’ve got right now, compared with previous images, we’ve already found some unusual objects,” McConnell said, including some unusual stars that undergo violent outbursts.
He said data gathered in this survey would allow astronomers to find out more about star formation and how galaxies and black holes evolve through statistical analyses.

Continued aid to Afghanistan vital for regional security: Kazakh president
Kazakhstan’s President Kassym-Jomart Tokayev has emphasized the continuation of humanitarian assistance to Afghanistan, stating that the ongoing provision of such aid plays an important role in ensuring regional security.
Speaking at the international conference “Peace and Trust” in Ashgabat, the capital of Turkmenistan, Tokayev described addressing complex humanitarian challenges and the reconstruction of Afghanistan as a necessity.
“To ensure regional security, we consider it essential to continue providing assistance to Afghanistan, including by strengthening international efforts to address complex humanitarian issues and the reconstruction of this country. Kazakhstan remains committed to supporting the people of Afghanistan through humanitarian aid, educational projects, trade development, and food security initiatives,” he said.
Meanwhile, experts believe that sustainable improvement of the humanitarian situation in Afghanistan requires broad cooperation from the international community and support for the country’s economic development.
“Investment can be defined as one of the fundamental drivers of the economic cycle, and whenever Afghan traders do not take their money out of the country and instead invest domestically, it naturally leads to greater growth and dynamism in Afghanistan’s economy,” said Abdul Zahoor Modabber, an economic analyst.
As the humanitarian crisis in Afghanistan continues, reports by international relief organizations indicate that millions of citizens of the country are in urgent need of food, health, and livelihood assistance.
The reduction in funding for aid organizations, the impacts of climate change, and the return of migrants have increased concerns about a further deterioration of the humanitarian situation in the country.

Sirajuddin Haqqani: A government that intimidates its people is not a true government
Khalifa Sirajuddin Haqqani, Minister of Interior of the Islamic Emirate of Afghanistan, said during a visit to Khost province on Friday that any government which rules through fear cannot be considered a true government.
“A government is one that is loved by its people, one that serves them with respect and compassion, and from whose behavior people learn ethics and sincerity,” he said.
Haqqani also stressed that Afghans who opposed the Islamic Emirate in the past should be tolerated and treated in a way that helps eliminate hostility and animosity, paving the way for national cohesion.
