In the nation's capital, a popular Facebook page is helping the city's lost pets find their way home. Dinny McGettigan is a dog-owner and he wants to know - who's behind the page, and how do they reunite so many pets each year?

We're about to take a break for 2017 but before we do, we wanted to answer a question about an iconic summer festival in Canberra - Summernats. Rebecca Pearse thinks it's an odd fit in Canberra, she wants to know how it came to be here, and if there are any women who attend.

Sam Robinson was chatting to a colleague at work, when something unusual came up. "Someone she had come across had heard that if a baby wasn't named within a fixed number of days ... then the government gets to name them," he said.

He wanted to know if this was true, and if so, whether the ACT Government had named any babies to date. What was the process, he wondered?

Digital journalist Elise Pianegonda went looking at the fine print of the ACT Government's Births, Deaths and Marriages practice manual.

Faye Powell has spent years driving down Commonwealth Avenue, and in that time she's noticed a lot of international flags. She wanted to know - how many are there, who looks after them and where are they kept?

Reporter Sonya Gee took Faye to the ACT Government's flag store in Fyshwick.

Gary Brown knew exactly what he wanted Curious Canberra to look into - it's something that's been at the back of his mind for years.

His question is about the south Canberra district of Woden, which he thinks has been named after an old Norse god. So how did this happen? Intern Dharshini Sundran and reporter Sonya Gee find out.

When single-use plastic bags were banned in 2011, some Canberrans found themselves without a steady supply of free plastic bags.

Colin Mckay was one of them. He asked: "Has the sale of kitchen tidy bags increased as a result of not having plastic bags?"

His worried that it had, and questioned whether the ban could be considered successful if that was the case.

Reporter Sonya Gee peered into a few Canberra bins to find out what was going on.

We receive a lot of questions about the weather, especially asking whether temperatures in Canberra are changing.

Questioner Jacqui White seems pretty sure that they are. She remembers it being warmer in May when she was growing up, whereas these days, she's convinced the month is colder.

So how has the weather changed according to the BOM? Reporter Aarti Betigeri spoke to climatologist Joel Lisonbee to find out.

Canberran Elias Hallaj has been thinking about how his city is perceived by the rest of the country - it's not always seen in the best light. Often it's quite the opposite. That made him wonder: Is capital city bashing an international phenomenon? In particular, he wanted to know if other countries have the equivalent of 'Canberra bashing'.

Reporter Siobhan Heanue makes a few overseas calls in search of an answer.

Scott Mollan grew up in Canberra and while he can't remember the city without Lake Burley Griffin, he's heard plenty of tales of the days before it existed. He's always wondered about one particular aspect - how the lake was filled and where the water came from. Digital journalist Elise Pianegonda went looking through the capital's archives to find the answer.

It's winter, and there's no better time to think and talk about heating. We're answering a question from Don Fletcher, who remembered hearing about an unusual heating system that was installed within the Geoscience Australia building some 20 years ago. What is geothermal energy? And will we see it in more buildings and houses in Australia? Digital journalist Jordan Hayne answers those questions.
