The Hubble Telescope Turns 30 This Year. Here's How Astronomers Will Celebrate. – Space.com

HONOLULU — Astronomers kicked off 2020 by welcoming the 30th anniversary year of NASA’s venerable Hubble Space Telescope here at their largest annual gathering.

During the first full day of the 235th American Astronomical Society conference (Jan. 5), a team of scientists affiliated with the instrument shared their highlights from the mission. Over the course of its decade in flight, the Hubble Space Telescope has produced not just scientific results, but also a host of iconic images of the universe around us.

“We flooded the world with jaw-dropping pictures, month after month and year after year,” Ray Villard, a long-time public affairs officer working on Hubble for the Space Telescope Science Institute that runs it, said during the event. “These pictures, they really have redefined the universe for public, and they speak to public at visceral and emotional level that is far beyond the scientific understanding.”

And as scientists emphasized throughout the presentation, many of Hubble’s impacts couldn’t have been predicted when the instrument launched. Take, for example, exoplanets, of which zero had been identified at Hubble’s launch in 1990. Now, scientists know of more than 4,000 such distant worlds, and the space telescope has been a vital tool for studying and identifying them.

Hubble has been a key instrument for directly imaging exoplanets, Nikole Lewis, an astrophysicist at Cornell University, said during the event. Scientists have never actually seen most of the exoplanets they have discovered, except for those that have been directly imaged — and Hubble’s data archives are allowing scientists to see more of these worlds.

“These were basically images that were taken before we knew those planets were there,” Lewis said. “We were able to dig back into the archives of these data and find planets that were just buried before.” That research can continue even after Hubble’s eventual demise.

Scientists are well aware that things could have gone very differently for Hubble. After the instrument launched in 1990, astronomers were dismayed to see that all its images were fuzzy. Engineers traced the problem to a manufacturing error in the telescope’s mirror.

But Hubble was special: It had been designed so that astronauts flying the space shuttle could repair it. In 1993, the first such mission launched and fixed Hubble’s infamous mirror issue; four additional servicing missions visited the instrument before the space shuttle was retired.

Since 2009, Hubble has been on its own. A couple of glitches in late 2018 and early 2019 reminded scientists how lucky they were to have the telescope. But overall, the grizzled spacecraft is doing well, Jennifer Wiseman, an astrophysicist at NASA’s Goddard Space Flight Center in Maryland, said during the panel. The gyros that allow the spacecraft to point at targets are lasting well, as are the batteries that run the machinery and the science instruments themselves.

And astronomers of all stripes are dedicated to getting every drop of Hubble data that they can. The mission is a vital for understanding our own neighborhood as well as the greater universe around us. Heidi Hammel, an astronomer at the Association of Universities for Research in Astronomy emphasized in particular the way the Hubble Space Telescope’s work benefits missions that NASA sends to visit solar system destinations.

It was the Hubble Space Telescope that allowed for last year’s record-breaking New Horizons flyby of a Kuiper Belt object now dubbed Arrokoth. That object wasn’t discovered until long after the spacecraft launched; it was Hubble images that spotted it and determined it could be a good target for the mission’s second act.

“It’s been a superb solar-system explorer and it will continue to be as long as it’s working,” Hammel said. “I’m a lifetime Hubble-hugger.”

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
